Weyl semimetallic phase in an interacting lattice system / V. Mastropietro. - In: JOURNAL OF STATISTICAL PHYSICS. - ISSN 0022-4715. - 157:4-5(2014), pp. 830-854. [10.1007/s10955-014-1020-0]
Abstract:
By using Wilsonian renormalization group methods we rigorously establish the existence of a Weyl semimetallic phase in an interacting three dimensional fermionic lattice system, by showing that the zero temperature Schwinger functions are asymptotically close to the ones of massless Dirac fermions. This is done via an expansion which is convergent in a region of parameters, which includes the quantum critical point discriminating between the semimetallic and the insulating phase.
