Today's #arXivsummary: https://arxiv.org/abs/2302.10590 by Mukherjee et. al. Authors perform a sequence of RG transformations on a system of 2D non-interacting Dirac fermions placed on a torus. Emergence of additional spatial dimension observed which arises out of the scaling of multipartite entanglement. For a strong transverse magnetic field, Luttinger's theorem breaks down. Relation found between the topological invariants of the metallic and the quantum Hall systems. #CondMat #StrEl #arXiv_2302_10590
