1 | Mishchenko, Eugene | Minimal conductivity in graphene: interaction corrections and ultraviolet anomaly | Conductivity of a disorder-free intrinsic graphene is studied to the first order in the long-range Coulomb interaction and is found to be ? = ?0(1+0.01g), where g is the dimensionless ("fine structure") coupling constant. The calculations are performed using three different methods: i) electron pola... | Optical conductivity | 2008-07-01 |
