Abstract: Dirac and Weyl semimetals with linearly crossing bands are the focus of much recent interest in condensed matter physics. Although they host fascinating phenomena, their physics can be understood in terms of weakly interacting electrons.… read more here.

DOI: 10.1088/1674-1056/27/2/027402
Abstract: We study the superfuild ground state of ultracold fermions in optical lattices with a quadratic band touching. Examples are a checkerboard lattice around half filling and a kagome lattice above one third filling. Instead of… read more here.

DOI: 10.1103/physrevb.102.134204
Abstract: We investigate the impacts of combination of fermion-fermion interactions and impurity scatterings on the low-energy stabilities of two-dimensional asymmetric materials with a quadratic band-crossing point by virtue of the renormalization group that allows us to… read more here.
