Dynamical crossovers in prethermal critical states
Alessio Chiocchetta, Andrea Gambassi, Sebastian Diehl +1
We study the prethermal dynamics of an interacting quantum field theory with a N-component order parameter and symmetry, suddenly quenched in the vicinity of a dynamical cri…
Universal short-time dynamics: boundary functional renormalization group for a temperature quench
Alessio Chiocchetta, Andrea Gambassi, Sebastian Diehl +1
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 critica…
Short-time universal scaling and light-cone dynamics after a quench in an isolated quantum system in spatial dimensions
Alessio Chiocchetta, Marco Tavora, Andrea Gambassi +1
We investigate the effects of fluctuations on the dynamics of an isolated quantum system represented by a field theory with symmetry after a quench in spatial di…
