An effective scheme is proposed to generate the singlet state with three four-level atoms trapped in three distant cavities connected with each other by three optical fibers,respectively.The ground st
Hybridizing collective spin excitations and a cavity with high cooperativity provides a new research subject in the field of cavity quantum electrodynamics and can also have potential applications to
A tunable double optomechanically induced transparency(OMIT)with a squeezed field is investigated in a system consisting of an optomechanical cavity coupled to a charged nanomechanical resonator via C
