Today's #arXivsummary: https://arxiv.org/abs/2308.09745 by Kim & Polkovnikov. Authors consider the interplay between integrability and quantum chaos in two generic models of spin chains that are parameterized by two independent couplings. It is expected that generic systems will dynamically self-tune themselves to integrable or nearly integrable regimes. #CondMat #arXiv_2308_09745
