Partially gapped fermions in 2D
Jonas de Woul, Edwin Langmann
We compute mean field phase diagrams of two closely related interacting fermion models in two spatial dimensions (2D). The first is the so-called 2D t-t'-V model describing spinles…

A 2D Luttinger model
Edwin Langmann
A detailed derivation of a two dimensional (2D) low energy effective model for spinless fermions on a square lattice with local interactions is given. This derivation utilizes a pa…
