@article{Tsuji2013NonthermalAO, title={Nonthermal antiferromagnetic order and nonequilibrium criticality in the Hubbard model.}, author={Naoto Tsuji and Martin Eckstein and Philipp Werner}, journal={Physical review letters}, year={2013}, volume={110 13}, pages={ 136404 } }

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…

Universal Prethermal Dynamics in Gross-Neveu-Yukawa Criticality.

- Physics, MedicinePhysical review letters
- 2019

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.

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.
