Detailed Description

Square lattice model.

The Square lattice allows for nearest-neighbor or next nearest-neighbor Models on a square lattice to be set up easily. A Model with the side lengths SIZE_X and SIZE_Y is created as follows.

Model model = Models::SquareLattice({SIZE_X, SIZE_Y}, {U, t, tp});

Here U is the on-site potential, t is the nearest neighbor hopping amplitude, and tp is an optional next-nearest neighbor hopping amplitude.

It is also possible to create a spinful model by adding a IDX_SPIN flag as follows.

Model model = Models::SquareLattice(
  {SIZE_X, SIZE_Y, IDX_SPIN},
  {U, t, tp}
);

The resulting Model has not yet been constructed, which means that it is possible to add further HoppingAmplitudes to it. Before using it, remember to call

model.construct();

◆ SquareLattice()

TBTK::Models::SquareLattice::SquareLattice	(	const Index &	size,
		const std::vector< std::complex< double >> &	parameters
	)

Constructs a square lattice.

Parameters

size	The size of the lattice. One Subindex can have the value IDX_SPIN to indicate a spin Subindex. Must have two components (plus one if IDX_SPIN is included).
parameters	The Model parameters. Must have two components, where the first component is the on-site term, and the second is the nearest neighbor hopping amplitude.
