Slow crossover from superdiffusion to diffusion in isotropic spin chains
C McCarthy, S Gopalakrishnan, R Vasseur - Physical Review B, 2024 - APS
Finite-temperature spin transport in integrable isotropic spin chains (ie, spin chains with
continuous non-Abelian symmetries) is known to be superdiffusive, with anomalous …

Observation of Ballistic Thermal Transport in a Nonintegrable Classical Many-Body System
J Wang, D Xiong - arXiv preprint arXiv:2402.02142, 2024 - arxiv.org
We report, for the first time, the observation of ballistic thermal transport in a nonintegrable
classical many-body system. This claim is substantiated by appropriately incorporating long …
