We study dynamical phase transitions from antiferromagnetic to paramagnetic states driven by an interaction quench in the fermionic Hubbard model using the nonequilibrium dynamical mean-field theory. We identify two dynamical transition points where the relaxation behavior qualitatively changes: one corresponds to the thermal phase transition at which the order parameter decays critically slowly in a power law ∝t(-1/2), and the other is connected to the existence of nonthermal antiferromagnetic… 
Nonthermal Melting of Néel Order in the Hubbard Model
We study the unitary time evolution of antiferromagnetic order in the Hubbard model after a quench starting from the perfect Neel state. In this setup, which is well suited for experiments with cold
Prethermalization and persistent order in the absence of a thermal phase transition
We numerically study the dynamics after a parameter quench in the one-dimensional transverse -field Ising model with long-range interactions (alpha 1/r(alpha) with distance r), for finite chains and
Nonequilibrium dynamics of superconductivity in the attractive Hubbard model
We present a framework of semiclassical superconductivity (SC) dynamics that properly includes effects of spatial fluctuations for the attractive Hubbard model. We consider both coherent and
Universal Prethermal Dynamics in Gross-Neveu-Yukawa Criticality.
TLDR
The prethermal dynamics of the Gross-Neveu-Yukawa quantum field theory, suddenly quenched in the vicinity of a critical point, is found to be controlled by two fixed points depending on the size of the quench, and the temporal crossover between the universal scaling regimes governed by the two universality classes is explored.
Resonant Thermalization of Periodically Driven Strongly Correlated Electrons.
TLDR
The dynamics of the Fermi-Hubbard model driven by a time-periodic modulation of the interaction within nonequilibrium dynamical mean-field theory are studied and the existence of a critical frequency at which the system rapidly thermalizes despite the large interaction is shown.
Nonthermal switching of charge order: dynamical slowing down and optimal control
We investigate the laser-induced dynamics of electronically driven charge-density-wave order. A comprehensive mean-field analysis of the attractive Hubbard model in the weak-coupling regime reveals
From sudden quench to adiabatic dynamics in the attractive Hubbard model
We study the crossover between the sudden quench limit and the adiabatic dynamics of superconducting states in the attractive Hubbard model. We focus on the dynamics induced by the change of the
Concurrence of dynamical phase transitions at finite temperature in the fully connected transverse-field Ising model
We construct the finite-temperature dynamical phase diagram of the fully connected transverse-field Ising model from the vantage point of two disparate concepts of dynamical criticality. An
Dynamic inhomogeneities and phase separation after quantum quenches in strongly correlated systems
We present a Gutzwiller von Neumann dynamics (GvND) method for simulating equilibrium and nonequilibrium phenomena in strongly correlated electron systems. Our approach is a real-space formulation of
Momentum-dependent relaxation dynamics of the doped repulsive Hubbard model
We study the dynamical behavior of doped electronic systems subject to a global ramp of the repulsive Hubbard interaction. We start with formulating a real-time generalization of the
