Interconnected renormalization of Hubbard bands and Green's function zeros in Mott insulators induced by strong magnetic fluctuations
EA Stepanov, M Chatzieleftheriou, N Wagner… - Physical Review B, 2024 - APS
We analyze the role of spatial electronic correlations and, in particular, of the magnetic
fluctuations in Mott insulators. A half-filled Hubbard model is solved at large strength of the …
