Universal dynamics and non-thermal fixed points in quantum fluids far from equilibrium

AN Mikheev, I Siovitz, T Gasenzer - The European Physical Journal …, 2023 - Springer
Closed quantum systems far from thermal equilibrium can show universal dynamics near
attractor solutions, known as non-thermal fixed points, generically in the form of scaling …

Universal equation of state for wave turbulence in a quantum gas

LH Dogra, G Martirosyan, TA Hilker, JAP Glidden… - Nature, 2023 - nature.com
Boyle's 1662 observation that the volume of a gas is, at constant temperature, inversely
proportional to pressure, offered a prototypical example of how an equation of state (EoS) …

Prescaling relaxation to nonthermal attractors

MP Heller, A Mazeliauskas, T Preis - Physical Review Letters, 2024 - APS
We study how isotropic and homogeneous far-from-equilibrium quantum systems relax to
nonthermal attractors, which are of interest for cold atoms and nuclear collisions. We …
