Colloquium: Quantum and classical discrete time crystals

MP Zaletel, M Lukin, C Monroe, C Nayak, F Wilczek… - Reviews of Modern …, 2023 - APS
The spontaneous breaking of time-translation symmetry has led to the discovery of a new
phase of matter: the discrete time crystal. Discrete time crystals exhibit rigid subharmonic …

Band structure engineering and non-equilibrium dynamics in Floquet topological insulators

MS Rudner, NH Lindner - Nature reviews physics, 2020 - nature.com
Non-equilibrium topological phenomena can be induced in quantum many-body systems
using time-periodic fields (for example, by laser or microwave illumination). This Review …

Dynamical obstruction to localization in a disordered spin chain

D Sels, A Polkovnikov - Physical Review E, 2021 - APS
We analyze a one-dimensional XXZ spin chain in a disordered magnetic field. As the main
probes of the system's behavior, we use the sensitivity of eigenstates to adiabatic …

QuSpin: a Python package for dynamics and exact diagonalisation of quantum many body systems. Part II: bosons, fermions and higher spins

P Weinberg, M Bukov - SciPost Physics, 2019 - scipost.org
We present a major update to QuSpin, SciPostPhys. 2.1. 003--an open-source Python
package for exact diagonalization and quantum dynamics of arbitrary boson, fermion and …

Floquet prethermalization in a bose-hubbard system

A Rubio-Abadal, M Ippoliti, S Hollerith, D Wei, J Rui… - Physical Review X, 2020 - APS
Periodic driving has emerged as a powerful tool in the quest to engineer new and exotic
quantum phases. While driven many-body systems are generically expected to absorb …

Classical prethermal phases of matter

A Pizzi, A Nunnenkamp, J Knolle - Physical Review Letters, 2021 - APS
Systems subject to a high-frequency drive can spend an exponentially long time in a
prethermal regime, in which novel phases of matter with no equilibrium counterpart can be …

Thermalization of dilute impurities in one-dimensional spin chains

D Sels, A Polkovnikov - Physical Review X, 2023 - APS
We analyze a crossover between ergodic and nonergodic regimes in an interacting spin
chain with a dilute density of impurities, defined as spins with a strong local field. The dilute …

Floquet prethermalization with lifetime exceeding 90 s in a bulk hyperpolarized solid

W Beatrez, O Janes, A Akkiraju, A Pillai, A Oddo… - Physical review …, 2021 - APS
We report the observation of long-lived Floquet prethermal states in a bulk solid composed
of dipolar-coupled C 13 nuclei in diamond at room temperature. For precessing nuclear …

Floquet phases of matter via classical prethermalization

B Ye, F Machado, NY Yao - Physical Review Letters, 2021 - APS
We demonstrate that the prethermal regime of periodically driven (Floquet), classical many-
body systems can host nonequilibrium phases of matter. In particular, we show that there …

Digital quantum simulation, trotter errors, and quantum chaos of the kicked top

LM Sieberer, T Olsacher, A Elben, M Heyl… - npj Quantum …, 2019 - nature.com
This work aims at giving Trotter errors in digital quantum simulation (DQS) of collective spin
systems an interpretation in terms of quantum chaos of the kicked top. In particular, for DQS …
