Abstract: We investigate energy diffusion in long-range interacting spin systems, where the interaction decays algebraically as V(r)∝r^{-α} with the distance r between the sites. We consider prototypical spin systems, the transverse Ising model, and the XYZ… read more here.

Abstract: While the high-temperature spin diffusion in spin chains with random local fields has been the subject of numerous studies concerning the phenomenon of many-body localization (MBL), the energy diffusion in the same models has been… read more here.
