Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, , , , | Summary: We consider Lifshitz criticality (LC) with the dynamical critical exponent $z=2$ in one-dimensional interacting fermions with a filled Dirac Sea. We report that interactions have crucial effects on Lifshitz criticality. Single particle excitations are destabilized by interaction and decay into […]
