Classical many-body chaos with and without quasiparticles
(2020-11-09)
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 settings with and without symmetry breaking and ...
Anomalous dynamics and equilibration in the classical Heisenberg chain
(2021-08-26)
The search for departures from standard hydrodynamics in many-body systems has yielded a number of promising leads, especially in low dimension. Here we study one of the simplest classical interacting lattice models, the ...
Temperature dependence of butterfly effect in a classical many-body System
(2018-08-06)
We study the chaotic dynamics in a classical many-body system of interacting spins on the kagome lattice. We characterise many-body chaos via the butter y effect as captured by an appropriate out-of-time-ordered correlator. ...
