Today's #arXivsummary: https://arxiv.org/abs/2303.09573 by Stahl et. al. Authors examine the hydrodynamics of systems with spontaneously broken multipolar symmetries using systematic effective field theory. In absence of any SSB, quartic subdiffusion found. With both charge and dipole symmetries broken, quadratically propagating (and quartically subdiffusing) mode found. #CondMat #StatMech #arXiv_2303_09573
