Reproducing fourfold degeneracy in entanglement spectrum of Bose-Hubbard model
Hi all, So according to the paper https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.113.020401 here, within certain ranges of U and V we should expect fourfold degeneracy of the first four lowest values of entanglement spectrum which signify the emergency of HI phase. I am trying to reproduc...
