Nonequilibrium time evolution and rephasing in the quantum sine-Gordon model
- PhysicsPhysical Review A
- 2019
We discuss the non-equilibrium time evolution of the phase field in the sine-Gordon model using two very different approaches: the truncated Wigner approximation and the truncated conformal space…
Non-thermal fixed points: Universal dynamics far from equilibrium
- PhysicsJulian Schwinger Centennial Conference
- 2019
In this article we give an overview of the concept of universal dynamics near non-thermal fixed points in isolated quantum many-body systems. We outline a non-perturbative kinetic theory derived…
Sudden interaction quench in the quantum sine-Gordon model
- Physics
- 2010
We study a sudden interaction quench in the weak-coupling regime of the quantum sine-Gordon model. The real time dynamics of the bosonic mode occupation numbers is calculated using the flow equation…
Universal dynamics of a turbulent superfluid Bose gas
- PhysicsPhysical Review A
- 2022
We study the emergence of universal scaling in the time-evolving momentum distribution of a harmonically trapped three-dimensional Bose-Einstein condensate, parametrically driven to a turbulent…
Kinetic theory of nonthermal fixed points in a Bose gas
- PhysicsPhysical Review A
- 2019
We outline a kinetic theory of non-thermal fixed points for the example of a dilute Bose gas, partially reviewing results obtained earlier, thereby extending, complementing, generalizing and…
Nonlinear critical slowing down of the one-component Ginzburg-Landau field
- Physics
- 1979
We discuss nonlinear relaxation processes of the one-component Ginzburg-Landau field that occur near the critical point after a sudden change in temperature or in the symmetry breaking field. A…
Universal short-time dynamics: boundary functional renormalization group for a temperature quench
- Physics
- 2016
We present a method to calculate short-time non-equilibrium universal exponents within the functional renormalization-group scheme. As an example, we consider the classical critical dynamics of the…
