Floquet dynamical quantum phase transitions

K Yang, L Zhou, W Ma, X Kong, P Wang, X Qin, X Rong… - Physical Review B, 2019 - APS
Dynamical quantum phase transitions (DQPTs) are manifested by time-domain nonanalytic
behaviors of many-body systems. Introducing a quench is so far understood as a typical …

Observation of dynamical phase transitions in a topological nanomechanical system

T Tian, Y Ke, L Zhang, S Lin, Z Shi, P Huang, C Lee… - Physical Review B, 2019 - APS
Dynamical phase transitions (DPTs), characterized by nonanalytic behaviors in time domain,
extend the equilibrium phase transitions to far-from-equilibrium situations. It has been …

Measuring a dynamical topological order parameter in quantum walks

XY Xu, QQ Wang, M Heyl, JC Budich… - Light: Science & …, 2020 - nature.com
Quantum processes of inherent dynamical nature, such as quantum walks, defy a
description in terms of an equilibrium statistical physics ensemble. Until now, identifying the …

Consequences of integrability breaking in quench dynamics of pairing Hamiltonians

JA Scaramazza, P Smacchia, EA Yuzbashyan - Physical Review B, 2019 - APS
We study the collisionless dynamics of two classes of nonintegrable pairing models. One is
a Bardeen-Cooper-Schrieffer model with separable energy-dependent interactions, and the …

Spin-energy correlation in degenerate weakly interacting Fermi gases

S Pegahan, J Kangara, I Arakelyan, JE Thomas - Physical Review A, 2019 - APS
Weakly interacting Fermi gases exhibit rich collective dynamics in spin-dependent
potentials, arising from correlations between spin degrees of freedom and conserved single …

Quantum Dynamics in a Weakly Interacting Fermi Gas

P He - 2019 - search.proquest.com
In recent years, the study of non-equilibrium many-body quantum systems is gaining a great
deal of attention. Even though many-body systems are made of individual particles …
