text: 'Rotation of molecules embedded in He nanodroplets is explored by a combination
of fs laser-induced alignment experiments and angulon quasiparticle theory. We
demonstrate that at low fluence of the fs alignment pulse, the molecule and its
solvation shell can be set into coherent collective rotation lasting long enough
to form revivals. With increasing fluence, however, the revivals disappear --
instead, rotational dynamics as rapid as for an isolated molecule is observed
during the first few picoseconds. Classical calculations trace this phenomenon
to transient decoupling of the molecule from its He shell. Our results open novel
opportunities for studying non-equilibrium solute-solvent dynamics and quantum
thermalization. '

text: Selected universal experimental properties of high-temperature superconducting
(HTS) cuprates have been singled out in the last decade. One of the pivotal challenges
in this field is the designation of a consistent interpretation framework within
which we can describe quantitatively the universal features of those systems.
Here we analyze in a detailed manner the principal experimental data and compare
them quantitatively with the approach based on a single-band model of strongly
correlated electrons supplemented with strong antiferromagnetic (super)exchange
interaction (the so-called t−J−U model). The model rationale is provided by estimating
its microscopic parameters on the basis of the three-band approach for the Cu-O
plane. We use our original full Gutzwiller wave-function solution by going beyond
the renormalized mean-field theory (RMFT) in a systematic manner. Our approach
reproduces very well the observed hole doping (δ) dependence of the kinetic-energy
gain in the superconducting phase, one of the principal non-Bardeen-Cooper-Schrieffer
features of the cuprates. The calculated Fermi velocity in the nodal direction
is practically δ-independent and its universal value agrees very well with that
determined experimentally. Also, a weak doping dependence of the Fermi wave vector
leads to an almost constant value of the effective mass in a pure superconducting
phase which is both observed in experiment and reproduced within our approach.
An assessment of the currently used models (t−J, Hubbard) is carried out and the
results of the canonical RMFT as a zeroth-order solution are provided for comparison
to illustrate the necessity of the introduced higher-order contributions.

text: 'We investigate the effect of the electron-hole (e-h) symmetry breaking on
d-wave superconductivity induced by non-local effects of correlations in the generalized
Hubbard model. The symmetry breaking is introduced in a two-fold manner: by the
next-to-nearest neighbor hopping of electrons and by the charge-bond interaction
- the off-diagonal term of the Coulomb potential. Both terms lead to a pronounced
asymmetry of the superconducting order parameter. The next-to-nearest neighbor
hopping enhances superconductivity for h-doping, while diminishes it for e-doping.
The charge-bond interaction alone leads to the opposite effect and, additionally,
to the kinetic-energy gain upon condensation in the underdoped regime. With both
terms included, with similar amplitudes, the height of the superconducting dome
and the critical doping remain in favor of h-doping. The influence of the charge-bond
interaction on deviations from symmetry of the shape of the gap at the Fermi surface
in the momentum space is briefly discussed.'

text: "The Fermi-Hubbard model is one of the key models of condensed matter physics,
which holds a\r\n\r\npotential for explaining the mystery of high-temperature
superconductivity. Recent progress in\r\n\r\nultracold atoms in optical lattices
has paved the way to studying the model’s phase diagram using\r\n\r\nthe tools
of quantum simulation, which emerged as a promising alternative to the numerical\r\n\r\ncalculations
plagued by the infamous sign problem. However, the temperatures achieved using\r\n\r\nelaborate
laser cooling protocols so far have been too high to show the appearance of\r\n\r\nantiferromagnetic (AF)
and superconducting quantum phases directly. In this work, we demonstrate\r\n\r\nthat
using the machinery of dissipative quantum state engineering, one can observe
the emergence of\r\n\r\nthe AF order in the Fermi-Hubbard model with fermions
in optical lattices. The core of the approach\r\n\r\nis to add incoherent laser
scattering in such a way that the AF state emerges as the dark state of\r\n\r\nthe
driven-dissipative dynamics. The proposed controlled dissipation channels described
in this work\r\n\r\nare straightforward to add to already existing experimental
setups."

text: We study the interplay of nematic and superconducting order in the two-dimensional
Hubbard model and show that they can coexist, especially when superconductivity
is not the energetically dominant phase. Due to a breaking of the C4 symmetry,
the coexisting phase inherently contains admixture of the s-wave pairing components.
As a result, the superconducting gap exhibits nonstandard features including changed
nodal directions. Our results also show that in the optimally doped regime the
pure superconducting phase is typically unstable towards developing nematicity
(breaking of the C4 symmetry). This has implications for the cuprate high-Tc superconductors,
for which in this regime the so-called intertwined orders have recently been observed.
Namely, the coexisting phase may be viewed as a precursor to such more involved
patterns of symmetry breaking.

text: Superconductivity in heavy-fermion systems has an unconventional nature and
is considered to originate from the universal features of the electronic structure.
Here, the Anderson lattice model is studied by means of the full variational Gutzwiller
wave function incorporating nonlocal effects of the on-site interaction. We show
that the d-wave superconducting ground state can be driven solely by interelectronic
correlations. The proposed microscopic mechanism leads to a multigap superconductivity
with the dominant contribution due to f electrons and in the dx2−y2-wave channel.
Our results rationalize several important observations for CeCoIn5.

text: We study the superconducting phase of the Hubbard model using the Gutzwiller
variational wave function (GWF) and the recently proposed diagrammatic expansion
technique (DE-GWF). The DE-GWF method works on the level of the full GWF and in
the thermodynamic limit. Here, we consider a finite-size system to study the accuracy
of the results as a function of the system size (which is practically unrestricted).
We show that the finite-size scaling used, e.g. in the variational Monte Carlo
method can lead to significant, uncontrolled errors. The presented research is
the first step towards applying the DE-GWF method in studies of inhomogeneous
situations, including systems with impurities, defects, inhomogeneous phases,
or disorder.

text: We give a comprehensive introduction into a diagrammatic method that allows
for the evaluation of Gutzwiller wave functions in finite spatial dimensions.
We discuss in detail some numerical schemes that turned out to be useful in the
real-space evaluation of the diagrams. The method is applied to the problem of
d-wave superconductivity in a two-dimensional single-band Hubbard model. Here,
we discuss in particular the role of long-range contributions in our diagrammatic
expansion. We further reconsider our previous analysis on the kinetic energy gain
in the superconducting state.

text: The recently proposed diagrammatic expansion (DE) technique for the full Gutzwiller
wave function (GWF) is applied to the Anderson lattice model. This approach allows
for a systematic evaluation of the expectation values with full Gutzwiller wave
function in finite-dimensional systems. It introduces results extending in an
essential manner those obtained by means of the standard Gutzwiller approximation
(GA), which is variationally exact only in infinite dimensions. Within the DE-GWF
approach we discuss the principal paramagnetic properties and their relevance
to heavy-fermion systems. We demonstrate the formation of an effective, narrow
f band originating from atomic f-electron states and subsequently interpret this
behavior as a direct itineracy of f electrons; it represents a combined effect
of both the hybridization and the correlations induced by the Coulomb repulsive
interaction. Such a feature is absent on the level of GA, which is equivalent
to the zeroth order of our expansion. Formation of the hybridization- and electron-concentration-dependent
narrow f band rationalizes the common assumption of such dispersion of f levels
in the phenomenological modeling of the band structure of CeCoIn5. Moreover, it
is shown that the emerging f-electron direct itineracy leads in a natural manner
to three physically distinct regimes within a single model that are frequently
discussed for 4f- or 5f-electron compounds as separate model situations. We identify
these regimes as (i) the mixed-valence regime, (ii) Kondo/almost-Kondo insulating
regime, and (iii) the Kondo-lattice limit when the f-electron occupancy is very
close to the f-state half filling, ⟨nˆf⟩→1. The nonstandard features of the emerging
correlated quantum liquid state are stressed.
