Exactly stable collective oscillations in conformal field theory

Exactly stable collective oscillations in conformal field theory

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.

Zusammenfassung: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.
