Many-body effects on graphene conductivity: Quantum Monte Carlo calculations

Boyda, D. L. ; Braguta, V. V. ; Katsnelson, M. I. ; Ulybyshev, M. V.


Optical conductivity of graphene is studied using quantum Monte Carlo calculations. We start from a Euclidean current- current correlator and extract sigma(omega) from Green-Kubo relations using the Backus-Gilbert method. Calculations were performed both for long-range interactions and taking into account only the contact term. In both cases we vary interaction strength and study its influence on ...
