Replica symmetry breaking in cold atoms and spin glasses

摘要: We consider a system composed by N atoms trapped within multimode cavity, whose theoretical description is captured disordered Dicke model. show that in the resonant, zero field limit exactly realizes Sherrington-Kirkpatrick Upon redefinition of temperature, same dynamics realized dispersive, strong limit. This regime also gives access to spin-glass observables which can be used detect Replica Symmetry Breaking.
