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 …

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 …

Anomalous dynamics and equilibration in the classical Heisenberg chain

AJ McRoberts, T Bilitewski, M Haque, R Moessner - Physical Review B, 2022 - APS
The search for departures from standard hydrodynamics in many-body systems has yielded
a number of promising leads, especially in low dimensions. Here, we study one of the …

Domain wall dynamics in classical spin chains: Free propagation, subdiffusive spreading, and soliton emission

AJ McRoberts, T Bilitewski, M Haque, R Moessner - Physical Review Letters, 2024 - APS
The nonequilibrium dynamics of domain wall initial states in a classical anisotropic
Heisenberg chain exhibits a striking coexistence of apparently linear and nonlinear …

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 …

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 …

Probing chaos in the spherical p-spin glass model

L Correale, A Polkovnikov, M Schirò, A Silva - SciPost Physics, 2023 - scipost.org
We study the dynamics of a quantum $ p $-spin glass model starting from initial states
defined in microcanonical shells, in a classical regime. We compute different chaos …

Floquet prethermal order by disorder

HK **, J Knolle - Physical Review Research, 2024 - APS
Frustrated magnets can have accidental ground state degeneracies which may be lifted by
various forms of disorder, for example in the form of thermal or quantum fluctuations. This …
