Description:
Author(s): Sedigh Ghamari, Sung-Sik Lee, and Catherine Kallin We study a system of weakly interacting electrons described by the energy dispersion ξ ( k ) = k x 2 − k y 2 − μ in two dimensions within a renormalization group approach. This energy dispersion exhibits a neck-narrowing Lifshitz transition at the critical chemical potential μ c = 0 where a van Hove singularity dev… [Phys. Rev. B 92, 085112] Published Thu Aug 06, 2015
