text: We study a linear rotor in a bosonic bath within the angulon formalism. Our
focus is on systems where isotropic or anisotropic impurity-boson interactions
support a shallow bound state. To study the fate of the angulon in the vicinity
of bound-state formation, we formulate a beyond-linear-coupling angulon Hamiltonian.
First, we use it to study attractive, spherically symmetric impurity-boson interactions
for which the linear rotor can be mapped onto a static impurity. The well-known
polaron formalism provides an adequate description in this limit. Second, we consider
anisotropic potentials, and show that the presence of a shallow bound state with
pronounced anisotropic character leads to a many-body instability that washes
out the angulon dynamics.

text: Mathematical models often aim to describe a complicated mechanism in a cohesive
and simple manner. However, reaching perfect balance between being simple enough
or overly simplistic is a challenging task. Frequently, game-theoretic models
have an underlying assumption that players, whenever they choose to execute a
specific action, do so perfectly. In fact, it is rare that action execution perfectly
coincides with intentions of individuals, giving rise to behavioural mistakes.
The concept of incompetence of players was suggested to address this issue in
game-theoretic settings. Under the assumption of incompetence, players have non-zero
probabilities of executing a different strategy from the one they chose, leading
to stochastic outcomes of the interactions. In this article, we survey results
related to the concept of incompetence in classic as well as evolutionary game
theory and provide several new results. We also suggest future extensions of the
model and argue why it is important to take into account behavioural mistakes
when analysing interactions among players in both economic and biological settings.

text: 'Branching morphogenesis is a ubiquitous process that gives rise to high exchange
surfaces in the vasculature and epithelial organs. Lymphatic capillaries form
branched networks, which play a key role in the circulation of tissue fluid and
immune cells. Although mouse models and correlative patient data indicate that
the lymphatic capillary density directly correlates with functional output, i.e.,
tissue fluid drainage and trafficking efficiency of dendritic cells, the mechanisms
ensuring efficient tissue coverage remain poorly understood. Here, we use the
mouse ear pinna lymphatic vessel network as a model system and combine lineage-tracing,
genetic perturbations, whole-organ reconstructions and theoretical modeling to
show that the dermal lymphatic capillaries tile space in an optimal, space-filling
manner. This coverage is achieved by two complementary mechanisms: initial tissue
invasion provides a non-optimal global scaffold via self-organized branching morphogenesis,
while VEGF-C dependent side-branching from existing capillaries rapidly optimizes
local coverage by directionally targeting low-density regions. With these two
ingredients, we show that a minimal biophysical model can reproduce quantitatively
whole-network reconstructions, across development and perturbations. Our results
show that lymphatic capillary networks can exploit local self-organizing mechanisms
to achieve tissue-scale optimization.'

text: Alpha oscillations are a distinctive feature of the awake resting state of
the human brain. However, their functional role in resting-state neuronal dynamics
remains poorly understood. Here we show that, during resting wakefulness, alpha
oscillations drive an alternation of attenuation and amplification bouts in neural
activity. Our analysis indicates that inhibition is activated in pulses that last
for a single alpha cycle and gradually suppress neural activity, while excitation
is successively enhanced over a few alpha cycles to amplify neural activity. Furthermore,
we show that long-term alpha amplitude fluctuations—the “waxing and waning” phenomenon—are
an attenuation-amplification mechanism described by a power-law decay of the activity
rate in the “waning” phase. Importantly, we do not observe such dynamics during
non-rapid eye movement (NREM) sleep with marginal alpha oscillations. The results
suggest that alpha oscillations modulate neural activity not only through pulses
of inhibition (pulsed inhibition hypothesis) but also by timely enhancement of
excitation (or disinhibition).

text: 'We investigate the potential of Multi-Objective, Deep Reinforcement Learning
for stock and cryptocurrency single-asset trading: in particular, we consider
a Multi-Objective algorithm which generalizes the reward functions and discount
factor (i.e., these components are not specified a priori, but incorporated in
the learning process). Firstly, using several important assets (BTCUSD, ETHUSDT,
XRPUSDT, AAPL, SPY, NIFTY50), we verify the reward generalization property of
the proposed Multi-Objective algorithm, and provide preliminary statistical evidence
showing increased predictive stability over the corresponding Single-Objective
strategy. Secondly, we show that the Multi-Objective algorithm has a clear edge
over the corresponding Single-Objective strategy when the reward mechanism is
sparse (i.e., when non-null feedback is infrequent over time). Finally, we discuss
the generalization properties with respect to the discount factor. The entirety
of our code is provided in open-source format.'

text: Cold atomic gases have become a paradigmatic system for exploring fundamental
physics, which at the same time allows for applications in quantum technologies.
The accelerating developments in the field have led to a highly advanced set of
engineering techniques that, for example, can tune interactions, shape the external
geometry, select among a large set of atomic species with different properties,
or control the number of atoms. In particular, it is possible to operate in lower
dimensions and drive atomic systems into the strongly correlated regime. In this
review, we discuss recent advances in few-body cold atom systems confined in low
dimensions from a theoretical viewpoint. We mainly focus on bosonic systems in
one dimension and provide an introduction to the static properties before we review
the state-of-the-art research into quantum dynamical processes stimulated by the
presence of correlations. Besides discussing the fundamental physical phenomena
arising in these systems, we also provide an overview of the calculational and
numerical tools and methods that are commonly used, thus delivering a balanced
and comprehensive overview of the field. We conclude by giving an outlook on possible
future directions that are interesting to explore in these correlated systems.

text: 'The Regularised Inertial Dean–Kawasaki model (RIDK) – introduced by the authors
and J. Zimmer in earlier works – is a nonlinear stochastic PDE capturing fluctuations
around the meanfield limit for large-scale particle systems in both particle density
and momentum density. We focus on the following two aspects. Firstly, we set up
a Discontinuous Galerkin (DG) discretisation scheme for the RIDK model: we provide
suitable definitions of numerical fluxes at the interface of the mesh elements
which are consistent with the wave-type nature of the RIDK model and grant stability
of the simulations, and we quantify the rate of convergence in mean square to
the continuous RIDK model. Secondly, we introduce modifications of the RIDK model
in order to preserve positivity of the density (such a feature only holds in a
“high-probability sense” for the original RIDK model). By means of numerical simulations,
we show that the modifications lead to physically realistic and positive density
profiles. In one case, subject to additional regularity constraints, we also prove
positivity. Finally, we present an application of our methodology to a system
of diffusing and reacting particles. Our Python code is available in open-source
format.'

text: We study the out-of-equilibrium quantum dynamics of dipolar polarons, i.e.,
impurities immersed in a dipolar Bose-Einstein condensate, after a quench of the
impurity-boson interaction. We show that the dipolar nature of the condensate
and of the impurity results in anisotropic relaxation dynamics, in particular,
anisotropic dressing of the polaron. More relevantly for cold-atom setups, quench
dynamics is strongly affected by the interplay between dipolar anisotropy and
trap geometry. Our findings pave the way for simulating impurities in anisotropic
media utilizing experiments with dipolar mixtures.

text: "Mosaic analysis with double markers (MADM) technology enables the generation
of genetic mosaic tissue in mice and high-resolution phenotyping at the individual
cell level. Here, we present a protocol for isolating MADM-labeled cells with
high yield for downstream molecular analyses using fluorescence-activated cell
sorting (FACS). We describe steps for generating MADM-labeled mice, perfusion,
single-cell suspension, and debris removal. We then detail procedures for cell
sorting by FACS and downstream analysis. This protocol is suitable for embryonic
to adult mice.\r\nFor complete details on the use and execution of this protocol,

text: Quantum entanglement is a key resource in currently developed quantum technologies.
Sharing this fragile property between superconducting microwave circuits and optical
or atomic systems would enable new functionalities, but this has been hindered
by an energy scale mismatch of >104 and the resulting mutually imposed loss and
noise. In this work, we created and verified entanglement between microwave and
optical fields in a millikelvin environment. Using an optically pulsed superconducting
electro-optical device, we show entanglement between propagating microwave and
optical fields in the continuous variable domain. This achievement not only paves
the way for entanglement between superconducting circuits and telecom wavelength
light, but also has wide-ranging implications for hybrid quantum networks in the
context of modularization, scaling, sensing, and cross-platform verification.

text: "Nominally identical materials exchange net electric charge during contact
through a mechanism that is still debated. ‘Mosaic models’, in which surfaces
are presumed to consist of a random patchwork of microscopic donor/acceptor sites,
offer an appealing explanation for this phenomenon. However, recent experiments
have shown that global differences persist even between same-material samples,
which the standard mosaic framework does not account for. Here, we expand the
mosaic framework by incorporating global differences in the densities of donor/acceptor
sites. We develop\r\nan analytical model, backed by numerical simulations, that
smoothly connects the global and deterministic charge transfer of different materials
to the local and stochastic mosaic picture normally associated with identical
materials. Going further, we extend our model to explain the effect of contact
asymmetries during sliding, providing a plausible explanation for reversal of
charging sign that has been observed experimentally."

text: Recent quantum technologies have established precise quantum control of various
microscopic systems using electromagnetic waves. Interfaces based on cryogenic
cavity electro-optic systems are particularly promising, due to the direct interaction
between microwave and optical fields in the quantum regime. Quantum optical control
of superconducting microwave circuits has been precluded so far due to the weak
electro-optical coupling as well as quasi-particles induced by the pump laser.
Here we report the coherent control of a superconducting microwave cavity using
laser pulses in a multimode electro-optical device at millikelvin temperature
with near-unity cooperativity. Both the stationary and instantaneous responses
of the microwave and optical modes comply with the coherent electro-optical interaction,
and reveal only minuscule amount of excess back-action with an unanticipated time
delay. Our demonstration enables wide ranges of applications beyond quantum transductions,
from squeezing and quantum non-demolition measurements of microwave fields, to
entanglement generation and hybrid quantum networks.

text: We consider the ground state and the low-energy excited states of a system
of N identical bosons with interactions in the mean-field scaling regime. For
the ground state, we derive a weak Edgeworth expansion for the fluctuations of
bounded one-body operators, which yields corrections to a central limit theorem
to any order in 1/N−−√. For suitable excited states, we show that the limiting
distribution is a polynomial times a normal distribution, and that higher-order
corrections are given by an Edgeworth-type expansion.

text: Many human interactions feature the characteristics of social dilemmas where
individual actions have consequences for the group and the environment. The feedback
between behavior and environment can be studied with the framework of stochastic
games. In stochastic games, the state of the environment can change, depending
on the choices made by group members. Past work suggests that such feedback can
reinforce cooperative behaviors. In particular, cooperation can evolve in stochastic
games even if it is infeasible in each separate repeated game. In stochastic games,
participants have an interest in conditioning their strategies on the state of
the environment. Yet in many applications, precise information about the state
could be scarce. Here, we study how the availability of information (or lack thereof)
shapes evolution of cooperation. Already for simple examples of two state games
we find surprising effects. In some cases, cooperation is only possible if there
is precise information about the state of the environment. In other cases, cooperation
is most abundant when there is no information about the state of the environment.
We systematically analyze all stochastic games of a given complexity class, to
determine when receiving information about the environment is better, neutral,
or worse for evolution of cooperation.

text: "In this paper, we prove the convexity of trace functionals (A,B,C)↦Tr|BpACq|s,\r\nfor
parameters (p, q, s) that are best possible, where B and C are any n-by-n positive-definite
matrices, and A is any n-by-n matrix. We also obtain the monotonicity versions
of trace functionals of this type. As applications, we extend some results in
Carlen et al. (Linear Algebra Appl 490:174–185, 2016), Hiai and Petz (Publ Res
Inst Math Sci 48(3):525-542, 2012) and resolve a conjecture in Al-Rashed and Zegarliński
(Infin Dimens Anal Quantum Probab Relat Top 17(4):1450029, 2014) in the matrix
setting. Other conjectures in Al-Rashed and Zegarliński (Infin Dimens Anal Quantum
Probab Relat Top 17(4):1450029, 2014) will also be discussed. We also show that
some related trace functionals are not concave in general. Such concavity results
were expected to hold in different problems."

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: "Bundling crossings is a strategy which can enhance the readability\r\nof
graph drawings. In this paper we consider good drawings, i.e., we require that\r\nany
two edges have at most one common point which can be a common vertex or a\r\ncrossing.
Our main result is that there is a polynomial-time algorithm to compute an\r\n8-approximation
of the bundled crossing number of a good drawing with no toothed\r\nhole. In general
the number of toothed holes has to be added to the 8-approximation.\r\nIn the
special case of circular drawings the approximation factor is 8, this improves\r\nupon
the 10-approximation of Fink et al. [14]. Our approach also works with the same\r\napproximation
factor for families of pseudosegments, i.e., curves intersecting at most\r\nonce.
We also show how to compute a 9/2-approximation when the intersection graph of\r\nthe
pseudosegments is bipartite and has no toothed hole."

text: When in equilibrium, thermal forces agitate molecules, which then diffuse,
collide and bind to form materials. However, the space of accessible structures
in which micron-scale particles can be organized by thermal forces is limited,
owing to the slow dynamics and metastable states. Active agents in a passive fluid
generate forces and flows, forming a bath with active fluctuations. Two unanswered
questions are whether those active agents can drive the assembly of passive components
into unconventional states and which material properties they will exhibit. Here
we show that passive, sticky beads immersed in a bath of swimming Escherichia
coli bacteria aggregate into unconventional clusters and gels that are controlled
by the activity of the bath. We observe a slow but persistent rotation of the
aggregates that originates in the chirality of the E. coli flagella and directs
aggregation into structures that are not accessible thermally. We elucidate the
aggregation mechanism with a numerical model of spinning, sticky beads and reproduce
quantitatively the experimental results. We show that internal activity controls
the phase diagram and the structure of the aggregates. Overall, our results highlight
the promising role of active baths in designing the structural and mechanical
properties of materials with unconventional phases.
