Description:
Author(s): Carsten Bauer, Andreas Rückriegel, Anand Sharma, and Peter Kopietz Using a nonperturbative functional renormalization group approach, we calculate the renormalized quasiparticle velocity v ( k ) and the static dielectric function ε ( k ) of suspended graphene as functions of an external momentum k . Our numerical result for v ( k ) can be fitted by v ( k ) / v F = A + B ln ( Λ 0 / k ) , where… [Phys. Rev. B 92, 121409(R)] Published Thu Sep 24, 2015
