genFermiHubbard2band_dd()

Lattice syten::MPS::Lat::U1U1::genFermiHubbard2band_dd	(	Index const	,
		std::vector< Index >	types
	)

Generates a Fermi-Hubbard-Kanamori lattice for a 2band model with density density interaction.

Parameters

types

the type of each site. The sites differ by the j and j_z value.

i=0: band 1 s_z=1/2 i=1: band 1 s_z=-1/2 i=2: band 2 s_z=1/2 i=3: band 2 s_z=-1/2

Remarks

For a detailed discussion of the need for parity operators, see the documentation for the \( \textrm{U(1)} × \textrm{U(1)} \)-symmetric MPS-Fermi-Hubbard model.

Implemented Single-Site Operators

c, ch create and annihilate particles on each site. n measures the particle number (0, 1,). p measures the parity (+1, -1).
