Hydrodynamic Attractor in Ultracold Atoms

K Fujii, T Enss - Physical Review Letters, 2024 - APS
The hydrodynamic attractor is a concept that describes universal equilibration behavior in
which systems lose microscopic details before hydrodynamics becomes applicable. We …

Dynamics of a fermi gas quenched to unitarity

P Dyke, A Hogan, I Herrera, CCN Kuhn, S Hoinka… - Physical Review Letters, 2021 - APS
We present an experimental study of a two component Fermi gas following an interaction
quench into the superfluid phase. Starting with a weakly attractive gas in the normal phase …

Complex scaling flows in the quench dynamics of interacting particles

T Enss, N Cuadra Braatz, G Gori - Physical Review A, 2022 - APS
Many-body systems driven out of equilibrium can exhibit scaling flows of the quantum state.
For a sudden quench to resonant interactions between particles we construct a class of …

Interaction quenches in nonzero-temperature fermionic condensates

H Kurkjian, VE Colussi, P Dyke, C Vale, S Musolino - Physical Review A, 2024 - APS
We revisit the study of amplitude oscillations in a pair condensate of fermions after an
interaction quench, and generalize it to nonzero temperature. For small variations of the …

Controllable nonautonomous localized waves and dynamics for a quasi-1D Gross–Pitaevskii equation in Bose–Einstein condensations with attractive interaction

H Wang, H Yang, Y Tian, W Liu - Chaos: An Interdisciplinary Journal of …, 2024 - pubs.aip.org
This paper investigates dynamical behaviors and controllability of some nonautonomous
localized waves based on the Gross–Pitaevskii equation with attractive interatomic …

Dynamic virial theorem at nonequilibrium and applications

SG Peng - Physical Review A, 2023 - APS
We show that a variety of nonequilibrium dynamics of interacting many-body systems are
universally characterized by an elegant relation, which we call the dynamic virial theorem …

Scattering mechanism of work done on an ultracold Fermi gas by a time-dependent interaction

M Poprocký, P Lipavský - Physical Review A, 2023 - APS
We discuss the work done on repulsive ultracold Fermi gas via collisions tuned by a time-
dependent magnetic ramp. If the interaction is strengthened during binary collisions, the …

Universal dynamic scaling and Contact dynamics in quenched quantum gases

JN Cui, Z Zhou, M Sun - Frontiers of Physics, 2024 - Springer
Recently universal dynamic scaling is observed in several systems, which exhibit a
spatiotemporal self-similar scaling behavior, analogous to the spatial scaling near phase …

Non-equilibrium Dynamics of Fermi Polarons Driven by Time-dependent Interaction

F Yang, R Qi - arXiv e-prints, 2025 - ui.adsabs.harvard.edu
We systematically studied the dynamics of Fermi polarons driven by time-dependent
scattering length using a time-dependent variational method. Starting from the non …
