Today's #arXivsummary: https://arxiv.org/abs/2302.11742 by Liao et. al. Authors develop an incremental algorithm to compute the entanglement entropy at a fermionic deconfined quantum critical point with exceptional accuracy; reveals that the universal coefficient of the logarithmic correction is negative, which does not agree with the positivity requirement of the conformal field theory. #CondMat #StrEl #arXiv_2302_11742
