Exactly Stable Collective Oscillations in Conformal Field Theory
arXiv:1109.6013 · doi:10.1103/PhysRevD.85.105002
Abstract
Any conformal field theory (CFT) on a sphere supports completely undamped collective oscillations. We discuss the implications of this fact for studies of thermalization using AdS/CFT. Analogous oscillations occur in Galilean CFT, and they could be observed in experiments on ultracold fermions.
