Quenched coupling, entangled equilibria, and correlated composite operators: a tale of two O(N) models

open access: yesJournal of High Energy Physics, 2019
A macroscopic version of Einstein-Podolsky-Rosen entanglement is obtained by quenching a quadratic coupling between two O(N) vector models. A quench of the mixed vacuum produces an excited entangled state, reminiscent of purified thermal equilibrium ...

Real-space effects of a quench in the Su–Schrieffer–Heeger model and elusive dynamical appearance of the topological edge states

open access: yesNew Journal of Physics, 2022
The topological phase of the Su–Schrieffer–Heeger (SSH) model is known to exhibit two edge states that are topologically protected by the chiral symmetry. We demonstrate that, for any parameter quench performed on the half-filled SSH chain, the occupancy

Thermal quench effects on ferroelectric domain walls [PDF]

open access: yes, 2012
Using piezoresponse force microscopy on epitaxial ferroelectric thin films, we have measured the evolution of domain wall roughening as a result of heat-quench cycles up to 735C, with the effective roughness exponent \zeta\ changing from 0.25 to 0.5.

Saturation of the Quantum Null Energy Condition in Far-From-Equilibrium Systems [PDF]

open access: yes, 2017
The Quantum Null Energy Condition (QNEC) is a new local energy condition that a general Quantum Field Theory (QFT) is believed to satisfy, relating the classical null energy condition (NEC) to the second functional derivative of the entanglement entropy ...

Thermalization in quenched open quantum cosmology

open access: yesNuclear Physics B, 2023
In this article, we study the quantum field theoretic generalization of the Caldeira-Leggett model in general curved space-time considering interactions between two scalar fields in a classical gravitational background.

Holographic subregion complexity under a thermal quench

open access: yesJournal of High Energy Physics, 2018
We study the evolution of holographic subregion complexity under a thermal quench in this paper. From the subregion CV proposal in the AdS/CFT correspondence, the subregion complexity in the CFT is holographically captured by the volume of the ...

Solution for an interaction quench in the Lieb-Liniger Bose gas [PDF]

open access: yes, 2014
We study a quench protocol where the ground state of a free many-particle bosonic theory in one dimension is let unitarily evolve in time under the integrable Lieb-Liniger Hamiltonian of $\delta$-interacting repulsive bosons. By using a recently-proposed

Inhomogeneous Kibble-Zurek mechanism: vortex nucleation during Bose-Einstein condensation [PDF]

open access: yes, 2011
The Kibble-Zurek mechanism is applied to the spontaneous formation of vortices in a harmonically trapped thermal gas following a temperature quench through the critical value for Bose-Einstein condensation.

Slow relaxation and sensitivity to disorder in trapped lattice fermions after a quench [PDF]

open access: yes, 2016
We consider a system of non-interacting fermions in one dimension subject to a single-particle potential consisting of (a) a strong optical lattice, (b) a harmonic trap, and (c) uncorrelated on-site disorder.

Staged cooling of a fusion-grade plasma in a tokamak thermal quench

open access: yesNuclear Fusion, 2023
In tokamak disruptions where the magnetic connection length becomes comparable to or even shorter than the plasma mean-free-path, parallel transport can dominate the energy loss and the thermal quench of the core plasma goes through four phases (stages ...
