genFermiHubbardKNS()

MPS::Lattice syten::MPS::Lat::U1U1Z::genFermiHubbardKNS	(	Index const	width,
		Index const	length = 1,
		std::vector< Index >	types = std::vector<Index>()
	)

Generates a (possibly 2D) chain of momentum-space Fermi-Hubbard sites.

Symmetries are \( {\mathbb{Z}_L} \) for quasi-momentum, \( \mathrm{U}(1) \) for charge/particle conservation and \( \mathrm{U}(1) \) for spin along \(z\)-axis.

Parameters

width	The number of sites per ring
length	The number of rings, defaults to 1
types	the type of each site, type i has single-particle momentum i. If empty, generated on the fly assuming linear ordering.
