Observation of shock waves in a strongly interacting Fermi gas.
TLDR
The authors' simulations of the time-dependent density profiles agree very well with the data and provide clear evidence of shock wave formation in this universal quantum hydrodynamic system.
Soliton solutions of a Calogero model in a harmonic potential
A classical Calogero model in an external harmonic potential is known to be integrable for any number of particles. We consider here reductions which play a role of the 'soliton' solutions of the
Quantum quench and thermalization of one-dimensional Fermi gas via phase-space hydrodynamics
By exploring a phase-space hydrodynamics description of one-dimensional free Fermi gas, we discuss how systems settle down to steady states described by the generalized Gibbs ensembles through
Out-of-equilibrium open quantum systems: A comparison of approximate quantum master equation approaches with exact results
We present the Born-Markov approximated Redfield quantum master equation (RQME) description for an open system of noninteracting particles (bosons or fermions) on an arbitrary lattice of $N$ sites in
Finite-temperature dynamical structure factor of the one-dimensional Bose gas: From the Gross-Pitaevskii equation to the Kardar-Parisi-Zhang universality class of dynamical critical phenomena
We study the finite temperature dynamical structure factor $S(k,\omega)$ of a 1D Bose gas using numerical simulations of the Gross--Pitaevskii equation appropriate to a weakly interacting system. The
Fluctuating hydrodynamics for a discrete Gross-Pitaevskii equation: Mapping onto the Kardar-Parisi-Zhang universality class
We show that several aspects of the low-temperature hydrodynamics of a discrete Gross-Pitaevskii equation (GPE) can be understood by mapping it to a nonlinear version of fluctuating hydrodynamics.
Kardar-Parisi-Zhang scaling for an integrable lattice Landau-Lifshitz spin chain.
TLDR
This work studies the scaling behavior for the integrable lattice Landau-Lifshitz spin chain and finds strong evidence that the scaling function is identical to the one obtained from the stationary stochastic Burgers equation, alias Kardar-Parisi-Zhang equation.
Cavity-mediated near-critical dissipative dynamics of a driven condensate.
TLDR
In this system cavity-mediated long-range interactions between atoms, tunable by the drive strength, lead to softening of an excitation mode recently observed in experiments, explaining the nonmonotonic pump-dependent atomic damping rate observed in recent experiments.
Hydrodynamics of cold atomic gases in the limit of weak nonlinearity, dispersion and dissipation
Dynamics of interacting cold atomic gases have recently become a focus of both experimental and theoretical studies. Often cold atom systems show hydrodynamic behavior and support the propagation of
Cavity-coupled double-quantum dot at finite bias: Analogy with lasers and beyond
We present a theoretical and experimental study of photonic and electronic transport properties of a voltage biased InAs semiconductor double quantum dot (DQD) that is dipole coupled to a
