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

Abstract

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 Coulomb interaction. Such a double OMIT can be achieved by adjusting the strength of the Coulomb interaction and can be observed even with a single-photon squeezed field at finite temperature. Since it is robust against cavity decay but very sensitive to some parameters, such as the environmental temperature, the model under consideration can be applied as a quantum thermometer for precision measurement of the environmental temperature within the reach of current techniques.
