Today's #arXivsummary: https://arxiv.org/abs/2301.13218 by Khasseh et. al. Authors introduce an alternative indicator for quantum many-body integrability and chaos based on the statistics of eigenstates by means of nearest-neighbor subsystem trace
distances. Indicator signals the expected quantum many-body integrability. #CondMat #StatMech #arXiv_2301_13218
