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 …

Minimal model for fast scrambling

R Belyansky, P Bienias, YA Kharkov, AV Gorshkov… - Physical review …, 2020 - APS
We study quantum information scrambling in spin models with both long-range all-to-all and
short-range interactions. We argue that a simple global, spatially homogeneous interaction …

Higher-order and fractional discrete time crystals in clean long-range interacting systems

A Pizzi, J Knolle, A Nunnenkamp - Nature communications, 2021 - nature.com
Discrete time crystals are periodically driven systems characterized by a response with
periodicity n T, with T the period of the drive and n> 1. Typically, n is an integer and bounded …

Measurement-induced phase transition in a chaotic classical many-body system

J Willsher, SW Liu, R Moessner, J Knolle - Physical Review B, 2022 - APS
Local measurements in quantum systems are projective operations which act to counteract
the spread of quantum entanglement. Recent work has shown that local, random …

Robustness of Kardar-Parisi-Zhang scaling in a classical integrable spin chain with broken integrability

D Roy, A Dhar, H Spohn, M Kulkarni - Physical Review B, 2023 - APS
Recent investigations have observed superdiffusion in integrable classical and quantum
spin chains. An intriguing connection between these spin chains and the Kardar-Parisi …

Classical route to ergodicity and scarring in collective quantum systems

S Sinha, S Ray, S Sinha - Journal of Physics: Condensed Matter, 2024 - iopscience.iop.org
Ergodicity, a fundamental concept in statistical mechanics, is not yet a fully understood
phenomena for closed quantum systems, particularly its connection with the underlying …

Arresting classical many-body chaos by kinetic constraints

A Deger, S Roy, A Lazarides - Physical Review Letters, 2022 - APS
We investigate the effect of kinetic constraints on classical many-body chaos in a
translationally invariant Heisenberg spin chain using a classical counterpart of the out-of …

Classical many-body chaos with and without quasiparticles

T Bilitewski, S Bhattacharjee, R Moessner - Physical Review B, 2021 - APS
We study correlations, transport, and chaos in a Heisenberg magnet as a classical model
many-body system. By varying temperature and dimensionality, we can tune between …

Cavity-QED simulator of slow and fast scrambling

J Marino, AM Rey - Physical Review A, 2019 - APS
We study information scrambling, as diagnosed by the out-of-time order correlations
(OTOCs), in a system of large spins collectively interacting via spatially inhomogeneous and …

Bridging the gap between classical and quantum many-body information dynamics

A Pizzi, D Malz, A Nunnenkamp, J Knolle - Physical Review B, 2022 - APS
The fundamental question of how information spreads in closed quantum many-body
systems is often addressed through the lens of the bipartite entanglement entropy, a quantity …
