text: Quantum kinetically constrained models have recently attracted significant
attention due to their anomalous dynamics and thermalization. In this work, we
introduce a hitherto unexplored family of kinetically constrained models featuring
conserved particle number and strong inversion-symmetry breaking due to facilitated
hopping. We demonstrate that these models provide a generic example of so-called
quantum Hilbert space fragmentation, that is manifested in disconnected sectors
in the Hilbert space that are not apparent in the computational basis. Quantum
Hilbert space fragmentation leads to an exponential in system size number of eigenstates
with exactly zero entanglement entropy across several bipartite cuts. These eigenstates
can be probed dynamically using quenches from simple initial product states. In
addition, we study the particle spreading under unitary dynamics launched from
the domain wall state, and find faster than diffusive dynamics at high particle
densities, that crosses over into logarithmically slow relaxation at smaller densities.
Using a classically simulable cellular automaton, we reproduce the logarithmic
dynamics observed in the quantum case. Our work suggests that particle conserving
constrained models with inversion symmetry breaking realize so far unexplored
dynamical behavior and invite their further theoretical and experimental studies.

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: We present a numerical analysis of spin-1/2 fermions in a one-dimensional
harmonic potential in the presence of a magnetic point-like impurity at the center
of the trap. The model represents a few-body analogue of a magnetic impurity in
the vicinity of an s-wave superconductor. Already for a few particles we find
a ground-state level crossing between sectors with different fermion parities.
We interpret this crossing as a few-body precursor of a quantum phase transition,
which occurs when the impurity "breaks" a Cooper pair. This picture is further
corroborated by analyzing density-density correlations in momentum space. Finally,
we discuss how the system may be realized with existing cold-atoms platforms.

text: We employ the Gross-Pitaevskii equation to study acoustic emission generated
in a uniform Bose gas by a static impurity. The impurity excites a sound-wave
packet, which propagates through the gas. We calculate the shape of this wave
packet in the limit of long wave lengths, and argue that it is possible to extract
properties of the impurity by observing this shape. We illustrate here this possibility
for a Bose gas with a trapped impurity atom -- an example of a relevant experimental
setup. Presented results are general for all one-dimensional systems described
by the nonlinear Schrödinger equation and can also be used in nonatomic systems,
e.g., to analyze light propagation in nonlinear optical media. Finally, we calculate
the shape of the sound-wave packet for a three-dimensional Bose gas assuming a
spherically symmetric perturbation.

text: "The numerical simulation of dynamical phenomena in interacting quantum systems
is a notoriously hard problem. Although a number of promising numerical methods
exist, they often have limited applicability due to the growth of entanglement
or the presence of the so-called sign problem. In this work, we develop an importance
sampling scheme for the simulation of quantum spin dynamics, building on a recent
approach mapping quantum spin systems to classical stochastic processes. The importance
sampling scheme is based on identifying the classical trajectory that yields the
largest contribution to a given quantum observable. An exact transformation is
then carried out to preferentially sample trajectories that are close to the dominant
one. We demonstrate that this approach is capable of reducing the temporal growth
of fluctuations in the stochastic quantities, thus extending the range of accessible
times and system sizes compared to direct sampling. We discuss advantages and
limitations of the proposed approach, outlining directions\r\nfor further developments."

text: We investigate a mechanism to transiently stabilize topological phenomena
in long-lived quasi-steady states of isolated quantum many-body systems driven
at low frequencies. We obtain an analytical bound for the lifetime of the quasi-steady
states which is exponentially large in the inverse driving frequency. Within this
lifetime, the quasi-steady state is characterized by maximum entropy subject to
the constraint of fixed number of particles in the system's Floquet-Bloch bands.
In such a state, all the non-universal properties of these bands are washed out,
hence only the topological properties persist.
