Interacting type-II semi-Dirac quasiparticles
Mohamed M. Elsayed, Taras I. Lakoba, Valeri N. Kotov
Type-II semi-Dirac fermions in two dimensions have been proposed to describe topologically nontrivial low-energy excitations in titanium/vanadium oxide heterostructures. These quas…
Microscopic lattice model for quartic semi-Dirac fermions in two dimensions
Mohamed M. Elsayed, Valeri N. Kotov
We propose a lattice model for the realization of exotic quartic semi-Dirac fermions, i.e. quasiparticles exhibiting a dispersion with quartic momentum dependence in a given direct…
Coulomb interactions in systems of generalized semi-Dirac fermions
Mohamed M. Elsayed, Bruno Uchoa, Valeri N. Kotov
Interactions have strong effects in systems with flat bands. We examine the role of Coulomb interactions in two dimensional chiral anisotropic quasiparticles that disperse linearly…
