利用外源驱动介观RLC电路来制备压缩态光场

PREPARATION OF SQUEEZED STATE OF RADIATION FIELD IN A MESOSCOPIC RLC CIRCUIT DRIVEN BY AN EXTERNAL SOURCE

通过严格求解具有 SU(1 ,1 ) H (3)代数结构的含源介观 RL C电路系统 ,我们证明在外源驱动下的介观 RLC电路可得到具有明显量子压缩特性的光辐射 .

A time dependent Hermitian Hamiltonian with SU(1,1)H(3) algebraic structure is constructed to describe a mesoscopic RLC circuit with a source by quantizating the relevant classical equation of motion.Quantum dynamical problem corresponding to such a system is exactly solved by evolution operator method.It is shown that the squeezed state of radiation field in a mesoscopic RLC circuit driven by an external source can be prepared by the time evolution of the vacuum state.
