Discrete time crystals

DV Else, C Monroe, C Nayak… - Annual Review of …, 2020 - annualreviews.org
Experimental advances have allowed for the exploration of nearly isolated quantum many-
body systems whose coupling to an external bath is very weak. A particularly interesting …

Strong disorder RG approach–a short review of recent developments

F Iglói, C Monthus - The European Physical Journal B, 2018 - Springer
The strong disorder RG approach for random systems has been extended in many new
directions since our previous review of 2005 [F. Igloi, C. Monthus, Phys. Rep. 412, 277 …

Floquet engineering topological many-body localized systems

KSC Decker, C Karrasch, J Eisert, DM Kennes - Physical Review Letters, 2020 - APS
We show how second-order Floquet engineering can be employed to realize systems in
which many-body localization coexists with topological properties in a driven system. This …

Critical properties of the prethermal Floquet time crystal

M Natsheh, A Gambassi, A Mitra - Physical Review B, 2021 - APS
The critical properties characterizing the formation of the Floquet time crystal in the
prethermal phase are investigated analytically in the periodically driven O (N) model. In …

Activating critical exponent spectra with a slow drive

S Mathey, S Diehl - Physical Review Research, 2020 - APS
We uncover an aspect of the Kibble-Zurek phenomenology, according to which the spectrum
of critical exponents of a classical or quantum phase transition is revealed, by driving the …

Flow equations for disordered Floquet systems

SJ Thomson, D Magano, M Schirò - SciPost Physics, 2021 - scipost.org
In this work, we present a new approach to disordered, periodically driven (Floquet)
quantum many-body systems based on flow equations. Specifically, we introduce a …

Dynamic renormalization group theory for open Floquet systems

S Mathey, S Diehl - Physical Review B, 2020 - APS
We develop a comprehensive renormalization group (RG) approach to criticality in open
Floquet systems, where dissipation enables the system to reach a well-defined Floquet …

Superuniversality from disorder at two-dimensional topological phase transitions

B Kang, SA Parameswaran, AC Potter, R Vasseur… - Physical Review B, 2020 - APS
We investigate the effects of quenched randomness on topological quantum phase
transitions in strongly interacting two-dimensional systems. We focus first on transitions …

Dephasing-induced growth of discrete time-crystalline order in spin networks

A Sakurai, VM Bastidas, MP Estarellas, WJ Munro… - Physical Review B, 2021 - APS
A discrete time crystal (DTC) is a quantum phase of matter related to the symmetries of a
periodically driven system. It can appear when the initial state breaks these symmetries, and …

Quantum Hall network models as Floquet topological insulators

AC Potter, JT Chalker, V Gurarie - Physical Review Letters, 2020 - APS
Network models for equilibrium integer quantum Hall (IQH) transitions are described by
unitary scattering matrices that can also be viewed as representing nonequilibrium Floquet …
