Input parameter for Standard modeΒΆ

We show the following example of the input file.

model = "Hubbard"
lattice = "wannier90"
a0w = 2
a0l = 0
a0h = 2
a1w = 0
a1l = 2
a1h = 2
a2w = 1
a2l = 0
a2h = 0
2Sz = 0
nelec = 4
cutoff_t = 0.1
cutoff_u = 1.0
cutoff_j = 0.1

The input parameters for the Standard mode to perform calculation of the downfolded model are as follows:

  • lattice = "wannier90"

  • cutoff_t, cutoff_u, cutoff_j

    Type : float

    Default : 1.0e-8

    The cutoff for the hopping, Coulomb, exchange integrals. We ignore these integrals smaller than cutoffs.

  • W, L, Height

  • a0W, a0L, a0H, a1W, a1L, a1H, a2W, a2L, a2H

  • Wsub, Lsub, Hsub

  • a0Wsub, a0Lsub, a0Hsub, a1Wsub, a1Lsub, a1Hsub, a2Wsub, a2Lsub, a2Hsub

    The third dimension appears.
