Dynamical phase transitions in the collisionless pre-thermal states of isolated quantum systems: theory and experiments

J Marino, M Eckstein, MS Foster… - Reports on Progress in …, 2022 - iopscience.iop.org
We overview the concept of dynamical phase transitions (DPTs) in isolated quantum
systems quenched out of equilibrium. We focus on non-equilibrium transitions characterized …

One-dimensional quantum many body systems with long-range interactions

S Maity, U Bhattacharya, A Dutta - Journal of Physics A …, 2019 - iopscience.iop.org
The presence of algebraically decaying long-range interactions may alter the critical as well
as topological behaviour of a quantum many-body systems. However, when the interaction …

Dynamical preparation of Floquet Chern insulators

L D'Alessio, M Rigol - Nature communications, 2015 - nature.com
Realizing topological insulators is of great current interest because of their remarkable
properties and possible future applications. There are recent proposals based on Floquet …

Mixed state dynamical quantum phase transitions

U Bhattacharya, S Bandyopadhyay, A Dutta - Physical Review B, 2017 - APS
Preparing an integrable system in a mixed state described by a thermal density matrix, we
subject it to a sudden quench and explore the subsequent unitary dynamics. To address the …

Probing the role of long-range interactions in the dynamics of a long-range Kitaev chain

A Dutta, A Dutta - Physical Review B, 2017 - APS
We study the role of long-range interactions (more precisely, the long-range
superconducting gap term) on the nonequilibrium dynamics considering a long-range p …

Quench dynamics and zero-energy modes: The case of the Creutz model

R Jafari, H Johannesson, A Langari… - Physical Review B, 2019 - APS
In most lattice models, the closing of a band gap typically occurs at high-symmetry points in
the Brillouin zone. Differently, in the Creutz model—describing a system of spinless fermions …

Out of equilibrium higher-order topological insulator: Floquet engineering and quench dynamics

T Nag, V Juričić, B Roy - Physical Review Research, 2019 - APS
Higher-order topological (HOT) states, hosting topologically protected modes on lower-
dimensional boundaries, such as hinges and corners, have recently extended the realm of …

Topology of one-dimensional quantum systems out of equilibrium

M McGinley, NR Cooper - Physical review letters, 2018 - APS
We study the topological properties of one-dimensional systems undergoing unitary time
evolution. We show that symmetries possessed both by the initial wave function and by the …

Dynamical topological invariant after a quantum quench

C Yang, L Li, S Chen - Physical Review B, 2018 - APS
We show how to define a dynamical topological invariant for one-dimensional two-band
topological systems after a quantum quench. By analyzing general two-band models of …

Classification of topological insulators and superconductors out of equilibrium

M McGinley, NR Cooper - Physical Review B, 2019 - APS
We establish the existence of a topological classification of many-particle quantum systems
undergoing unitary time evolution. The classification naturally inherits phenomenology …
