dmrg.run() claims quartic Hamiltonian is zero
I am trying to find the ground state properties of a quartic fermionic model: class DipoleLadder(CouplingModel, MPOModel): def __init__(self, L, t, delta): fermion_site = FermionSite(conserve='N') lattice = Chain(L, fermion_site, bc='open', bc_MPS='finite') CouplingModel.__init__(self, lattice) tArr...
