Atomic collapse in graphene and cyclic RG flow
arXiv:1312.7399 · doi:10.1103/PhysRevD.89.061702
Abstract
In this Letter we consider the problem of screening of external charge in graphene from the cyclic RG flow viewpoint. The analogy with conformal Calogero model is used to suggest the interpretation of the tower of resonant states as tower of Efimov states.
