Precision measurement of the environmental temperature by tunable double optomechanically induced transparency with a squeezed field

摘要

A tunable double optomechanically induced transparency (OMIT) with a squeezedfield is investigated in a system consisting of an optomechanical cavitycoupled to a charged nanomechanical resonator via Coulomb interaction. Such adouble OMIT can be achieved by adjusting the strength of the Coulombinteraction, and observed even with a single-photon squeezed field at finitetemperature. Since it is robust against the cavity decay, but very sensitive tosome parameters, such as the environmental temperature, the model under ourconsideration can be applied as a quantum thermometer for precision measurementof the environmental temperature within the reach of current techniques.
