Today's #arXivsummary: https://arxiv.org/abs/2309.02483 by Gavensky et. al. Authors use Streda's formula to derive an expression for the many-body Chern number in terms of the single-particle interacting Green's function. Topological invariant may be split into two components; one component connected to Luttinger's theorem. #CondMat #arXiv_2309_02483
