text: The epitaxial growth of a strained Ge layer, which is a promising candidate
for the channel material of a hole spin qubit, has been demonstrated on 300 mm
Si wafers using commercially available Si0.3Ge0.7 strain relaxed buffer (SRB)
layers. The assessment of the layer and the interface qualities for a buried strained
Ge layer embedded in Si0.3Ge0.7 layers is reported. The XRD reciprocal space mapping
confirmed that the reduction of the growth temperature enables the 2-dimensional
growth of the Ge layer fully strained with respect to the Si0.3Ge0.7. Nevertheless,
dislocations at the top and/or bottom interface of the Ge layer were observed
by means of electron channeling contrast imaging, suggesting the importance of
the careful dislocation assessment. The interface abruptness does not depend on
the selection of the precursor gases, but it is strongly influenced by the growth
temperature which affects the coverage of the surface H-passivation. The mobility
of 2.7 × 105 cm2/Vs is promising, while the low percolation density of 3 × 1010
/cm2 measured with a Hall-bar device at 7 K illustrates the high quality of the
heterostructure thanks to the high Si0.3Ge0.7 SRB quality.

text: Recent experimental advances have inspired the development of theoretical
tools to describe the non-equilibrium dynamics of quantum systems. Among them
an exact representation of quantum spin systems in terms of classical stochastic
processes has been proposed. Here we provide first steps towards the extension
of this stochastic approach to bosonic systems by considering the one-dimensional
quantum quartic oscillator. We show how to exactly parameterize the time evolution
of this prototypical model via the dynamics of a set of classical variables. We
interpret these variables as stochastic processes, which allows us to propose
a novel way to numerically simulate the time evolution of the system. We benchmark
our findings by considering analytically solvable limits and providing alternative
derivations of known results.

text: The power factor of poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)
(PEDOT:PSS) film can be significantly improved by optimizing the oxidation level
of the film in oxidation and reduction processes. However, precise control over
the oxidation and reduction effects in PEDOT:PSS remains a challenge, which greatly
sacrifices both S and σ. Here, we propose a two-step post-treatment using a mixture
of ethylene glycol (EG) and Arginine (Arg) and sulfuric acid (H2SO4) in sequence
to engineer high-performance PEDOT:PSS thermoelectric films. The high-polarity
EG dopant removes the excess non-ionized PSS and induces benzenoid-to-quinoid
conformational change in the PEDOT:PSS films. In particular, basic amino acid
Arg tunes the oxidation level of PEDOT:PSS and prevents the films from over-oxidation
during H2SO4 post-treatment, leading to increased S. The following H2SO4 post-treatment
further induces highly orientated lamellar stacking microstructures to increase
σ, yielding a maximum power factor of 170.6 μW m−1 K−2 at 460 K. Moreover, a novel
trigonal-shape thermoelectric device is designed and assembled by the as-prepared
PEDOT:PSS films in order to harvest heat via a vertical temperature gradient.
An output power density of 33 μW cm−2 is generated at a temperature difference
of 40 K, showing the potential application for low-grade wearable electronic devices.

text: Optoelectronic effects differentiating absorption of right and left circularly
polarized photons in thin films of chiral materials are typically prohibitively
small for their direct photocurrent observation. Chiral metasurfaces increase
the electronic sensitivity to circular polarization, but their out-of-plane architecture
entails manufacturing and performance trade-offs. Here, we show that nanoporous
thin films of chiral nanoparticles enable high sensitivity to circular polarization
due to light-induced polarization-dependent ion accumulation at nanoparticle interfaces.
Self-assembled multilayers of gold nanoparticles modified with L-phenylalanine
generate a photocurrent under right-handed circularly polarized light as high
as 2.41 times higher than under left-handed circularly polarized light. The strong
plasmonic coupling between the multiple nanoparticles producing planar chiroplasmonic
modes facilitates the ejection of electrons, whose entrapment at the membrane–electrolyte
interface is promoted by a thick layer of enantiopure phenylalanine. Demonstrated
detection of light ellipticity with equal sensitivity at all incident angles mimics
phenomenological aspects of polarization vision in marine animals. The simplicity
of self-assembly and sensitivity of polarization detection found in optoionic
membranes opens the door to a family of miniaturized fluidic devices for chiral
photonics.

text: We investigate the local self-sustained process underlying spiral turbulence
in counter-rotating Taylor–Couette flow using a periodic annular domain, shaped
as a parallelogram, two of whose sides are aligned with the cylindrical helix
described by the spiral pattern. The primary focus of the study is placed on the
emergence of drifting–rotating waves (DRW) that capture, in a relatively small
domain, the main features of coherent structures typically observed in developed
turbulence. The transitional dynamics of the subcritical region, far below the
first instability of the laminar circular Couette flow, is determined by the upper
and lower branches of DRW solutions originated at saddle-node bifurcations. The
mechanism whereby these solutions self-sustain, and the chaotic dynamics they
induce, are conspicuously reminiscent of other subcritical shear flows. Remarkably,
the flow properties of DRW persist even as the Reynolds number is increased beyond
the linear stability threshold of the base flow. Simulations in a narrow parallelogram
domain stretched in the azimuthal direction to revolve around the apparatus a
full turn confirm that self-sustained vortices eventually concentrate into a localised
pattern. The resulting statistical steady state satisfactorily reproduces qualitatively,
and to a certain degree also quantitatively, the topology and properties of spiral
turbulence as calculated in a large periodic domain of sufficient aspect ratio

text: 'In this paper, we explore the stability and dynamical relevance of a wide
variety of steady, time-periodic, quasiperiodic, and chaotic flows arising between
orthogonally stretching parallel plates. We first explore the stability of all
the steady flow solution families formerly identified by Ayats et al. [“Flows
between orthogonally stretching parallel plates,” Phys. Fluids 33, 024103 (2021)],
concluding that only the one that originates from the Stokesian approximation
is actually stable. When both plates are shrinking at identical or nearly the
same deceleration rates, this Stokesian flow exhibits a Hopf bifurcation that
leads to stable time-periodic regimes. The resulting time-periodic orbits or flows
are tracked for different Reynolds numbers and stretching rates while monitoring
their Floquet exponents to identify secondary instabilities. It is found that
these time-periodic flows also exhibit Neimark–Sacker bifurcations, generating
stable quasiperiodic flows (tori) that may sometimes give rise to chaotic dynamics
through a Ruelle–Takens–Newhouse scenario. However, chaotic dynamics is unusually
observed, as the quasiperiodic flows generally become phase-locked through a resonance
mechanism before a strange attractor may arise, thus restoring the time-periodicity
of the flow. In this work, we have identified and tracked four different resonance
regions, also known as Arnold tongues or horns. In particular, the 1 : 4 strong
resonance region is explored in great detail, where the identified scenarios are
in very good agreement with normal form theory. '

text: 'Motivated by properties-controlling potential of the strain, we investigate
strain dependence of structure, electronic, and magnetic properties of Sr2IrO4
using complementary theoretical tools: ab-initio calculations, analytical approaches
(rigid octahedra picture, Slater-Koster integrals), and extended t−J model. We
find that strain affects both Ir-Ir distance and Ir-O-Ir angle, and the rigid
octahedra picture is not relevant. Second, we find fundamentally different behavior
for compressive and tensile strain. One remarkable feature is the formation of
two subsets of bond- and orbital-dependent carriers, a compass-like model, under
compression. This originates from the strain-induced renormalization of the Ir-O-Ir
superexchange and O on-site energy. We also show that under compressive (tensile)
strain, Fermi surface becomes highly dispersive (relatively flat). Already at
a tensile strain of 1.5%, we observe spectral weight redistribution, with the
low-energy band acquiring almost purely singlet character. These results can be
directly compared with future experiments.'

text: We report the observation of an anomalous nonlinear optical response of the
prototypical three-dimensional topological insulator bismuth selenide through
the process of high-order harmonic generation. We find that the generation efficiency
increases as the laser polarization is changed from linear to elliptical, and
it becomes maximum for circular polarization. With the aid of a microscopic theory
and a detailed analysis of the measured spectra, we reveal that such anomalous
enhancement encodes the characteristic topology of the band structure that originates
from the interplay of strong spin–orbit coupling and time-reversal symmetry protection.
The implications are in ultrafast probing of topological phase transitions, light-field
driven dissipationless electronics, and quantum computation.

text: Several Ising-type magnetic van der Waals (vdW) materials exhibit stable magnetic
ground states. Despite these clear experimental demonstrations, a complete theoretical
and microscopic understanding of their magnetic anisotropy is still lacking. In
particular, the validity limit of identifying their one-dimensional (1-D) Ising
nature has remained uninvestigated in a quantitative way. Here we performed the
complete mapping of magnetic anisotropy for a prototypical Ising vdW magnet FePS3
for the first time. Combining torque magnetometry measurements with their magnetostatic
model analysis and the relativistic density functional total energy calculations,
we successfully constructed the three-dimensional (3-D) mappings of the magnetic
anisotropy in terms of magnetic torque and energy. The results not only quantitatively
confirm that the easy axis is perpendicular to the ab plane, but also reveal the
anisotropies within the ab, ac, and bc planes. Our approach can be applied to
the detailed quantitative study of magnetism in vdW materials.

text: 'Lithium bis(trifluoromethylsulfonyl)imide (LiTFSI) based water-in-salt electrolytes
(WiSEs) has recently emerged as a new promising class of electrolytes, primarily
owing to their wide electrochemical stability windows (~3–4 V), that by far exceed
the thermodynamic stability window of water (1.23 V). Upon increasing the salt
concentration towards superconcentration the onset of the oxygen evolution reaction
(OER) shifts more significantly than the hydrogen evolution reaction (HER) does.
The OER shift has been explained by the accumulation of hydrophobic anions blocking
water access to the electrode surface, hence by double layer theory. Here we demonstrate
that the processes during oxidation are much more complex, involving OER, carbon
and salt decomposition by OER intermediates, and salt precipitation upon local
oversaturation. The positive shift in the onset potential of oxidation currents
was elucidated by combining several advanced analysis techniques: rotating ring-disk
electrode voltammetry, online electrochemical mass spectrometry, and X-ray photoelectron
spectroscopy, using both dilute and superconcentrated electrolytes. The results
demonstrate the importance of reactive OER intermediates and surface films for
electrolyte and electrode stability and motivate further studies of the nature
of the electrode.'

text: We study the effects of osmotic shocks on lipid vesicles via coarse-grained
molecular dynamics simulations by explicitly considering the solute in the system.
We find that depending on their nature (hypo- or hypertonic) such shocks can lead
to bursting events or engulfing of external material into inner compartments,
among other morphology transformations. We characterize the dynamics of these
processes and observe a separation of time scales between the osmotic shock absorption
and the shape relaxation. Our work consequently provides an insight into the dynamics
of compartmentalization in vesicular systems as a result of osmotic shocks, which
can be of interest in the context of early proto-cell development and proto-cell
compartmentalisation.

text: Recent discoveries have shown that, when two layers of van der Waals (vdW)
materials are superimposed with a relative twist angle between them, the electronic
properties of the coupled system can be dramatically altered. Here, we demonstrate
that a similar concept can be extended to the optics realm, particularly to propagating
phonon polaritons–hybrid light-matter interactions. To do this, we fabricate stacks
composed of two twisted slabs of a vdW crystal (α-MoO3) supporting anisotropic
phonon polaritons (PhPs), and image the propagation of the latter when launched
by localized sources. Our images reveal that, under a critical angle, the PhPs
isofrequency curve undergoes a topological transition, in which the propagation
of PhPs is strongly guided (canalization regime) along predetermined directions
without geometric spreading. These results demonstrate a new degree of freedom
(twist angle) for controlling the propagation of polaritons at the nanoscale with
potential for nanoimaging, (bio)-sensing, or heat management.

text: Confining molecules can fundamentally change their chemical and physical properties.
Confinement effects are considered instrumental at various stages of the origins
of life, and life continues to rely on layers of compartmentalization to maintain
an out-of-equilibrium state and efficiently synthesize complex biomolecules under
mild conditions. As interest in synthetic confined systems grows, we are realizing
that the principles governing reactivity under confinement are the same in abiological
systems as they are in nature. In this Review, we categorize the ways in which
nanoconfinement effects impact chemical reactivity in synthetic systems. Under
nanoconfinement, chemical properties can be modulated to increase reaction rates,
enhance selectivity and stabilize reactive species. Confinement effects also lead
to changes in physical properties. The fluorescence of light emitters, the colours
of dyes and electronic communication between electroactive species can all be
tuned under confinement. Within each of these categories, we elucidate design
principles and strategies that are widely applicable across a range of confined
systems, specifically highlighting examples of different nanocompartments that
influence reactivity in similar ways.

text: The interaction of strong near-infrared (NIR) laser pulses with wide-bandgap
dielectrics produces high harmonics in the extreme ultraviolet (XUV) wavelength
range. These observations have opened up the possibility of attosecond metrology
in solids, which would benefit from a precise measurement of the emission times
of individual harmonics with respect to the NIR laser field. Here we show that,
when high-harmonics are detected from the input surface of a magnesium oxide crystal,
a bichromatic probing of the XUV emission shows a clear synchronization largely
consistent with a semiclassical model of electron–hole recollisions in bulk solids.
On the other hand, the bichromatic spectrogram of harmonics originating from the
exit surface of the 200 μm-thick crystal is strongly modified, indicating the
influence of laser field distortions during propagation. Our tracking of sub-cycle
electron and hole re-collisions at XUV energies is relevant to the development
of solid-state sources of attosecond pulses.

text: 'The fundamental and practical importance of particle stabilization has motivated
various characterization methods for studying polymer brushes on particle surfaces.
In this work, we show how one can perform sensitive measurements of neutral polymer
coating on colloidal particles using a commercial zetameter and salt solutions.
By systematically varying the Debye length, we study the mobility of the polymer-coated
particles in an applied electric field and show that the electrophoretic mobility
of polymer-coated particles normalized by the mobility of non-coated particles
is entirely controlled by the polymer brush and independent of the native surface
charge, here controlled with pH, or the surface–ion interaction. Our result is
rationalized with a simple hydrodynamic model, allowing for the estimation of
characteristics of the polymer coating: the brush length L, and the Brinkman length
ξ, determined by its resistance to flows. We demonstrate that the Debye layer
provides a convenient and faithful probe to the characterization of polymer coatings
on particles. Because the method simply relies on a conventional zetameter, it
is widely accessible and offers a practical tool to rapidly probe neutral polymer
brushes, an asset in the development and utilization of polymer-coated colloidal
particles.'

text: Tracing the motion of macromolecules, viruses, and nanoparticles adsorbed
onto cell membranes is currently the most direct way of probing the complex dynamic
interactions behind vital biological processes, including cell signalling, trafficking,
and viral infection. The resulting trajectories are usually consistent with some
type of anomalous diffusion, but the molecular origins behind the observed anomalous
behaviour are usually not obvious. Here we use coarse-grained molecular dynamics
simulations to help identify the physical mechanisms that can give rise to experimentally
observed trajectories of nanoscopic objects moving on biological membranes. We
find that diffusion on membranes of high fluidities typically results in normal
diffusion of the adsorbed nanoparticle, irrespective of the concentration of receptors,
receptor clustering, or multivalent interactions between the particle and membrane
receptors. Gel-like membranes on the other hand result in anomalous diffusion
of the particle, which becomes more pronounced at higher receptor concentrations.
This anomalous diffusion is characterised by local particle trapping in the regions
of high receptor concentrations and fast hopping between such regions. The normal
diffusion is recovered in the limit where the gel membrane is saturated with receptors.
We conclude that hindered receptor diffusivity can be a common reason behind the
observed anomalous diffusion of viruses, vesicles, and nanoparticles adsorbed
on cell and model membranes. Our results enable direct comparison with experiments
and offer a new route for interpreting motility experiments on cell membranes.

text: Efficient isomerization of photochromic molecules often requires conformational
freedom and is typically not available under solvent-free conditions. Here, we
report a general methodology allowing for reversible switching of such molecules
on the surfaces of solid materials. Our method is based on dispersing photochromic
compounds within polysilsesquioxane nanowire networks (PNNs), which can be fabricated
as transparent, highly porous, micrometer-thick layers on various substrates.
We found that azobenzene switching within the PNNs proceeded unusually fast compared
with the same molecules in liquid solvents. Efficient isomerization of another
photochromic system, spiropyran, from a colorless to a colored form was used to
create reversible images in PNN-coated glass. The coloration reaction could be
induced with sunlight and is of interest for developing “smart” windows.

text: We demonstrate a method for manipulating small ensembles of vortices in multiply
connected superconducting structures. A micron-size magnetic particle attached
to the tip of a silicon cantilever is used to locally apply magnetic flux through
the superconducting structure. By scanning the tip over the surface of the device
and by utilizing the dynamical coupling between the vortices and the cantilever,
a high-resolution spatial map of the different vortex configurations is obtained.
Moving the tip to a particular location in the map stabilizes a distinct multivortex
configuration. Thus, the scanning of the tip over a particular trajectory in space
permits nontrivial operations to be performed, such as braiding of individual
vortices within a larger vortex ensemble—a key capability required by many proposals
for topological quantum computing.

text: The development of strategies to assemble microscopic machines from dissipative
building blocks are essential on the route to novel active materials. We recently
demonstrated the hierarchical self-assembly of phoretic microswimmers into self-spinning
microgears and their synchronization by diffusiophoretic interactions [Aubret
et al., Nat. Phys., 2018]. In this paper, we adopt a pedagogical approach and
expose our strategy to control self-assembly and build machines using phoretic
phenomena. We notably introduce Highly Inclined Laminated Optical sheets microscopy
(HILO) to image and characterize anisotropic and dynamic diffusiophoretic interactions,
which cannot be performed by conventional fluorescence microscopy. The dynamics
of a (haematite) photocatalytic material immersed in (hydrogen peroxide) fuel
under various illumination patterns is first described and quantitatively rationalized
by a model of diffusiophoresis, the migration of a colloidal particle in a concentration
gradient. It is further exploited to design phototactic microswimmers that direct
towards the high intensity of light, as a result of the reorientation of the haematite
in a light gradient. We finally show the assembly of self-spinning microgears
from colloidal microswimmers and carefully characterize the interactions using
HILO techniques. The results are compared with analytical and numerical predictions
and agree quantitatively, stressing the important role played by concentration
gradients induced by chemical activity to control and design interactions. Because
the approach described hereby is generic, this works paves the way for the rational
design of machines by controlling phoretic phenomena.
