  • Title: Fluctuation-dissipation relation in a resonantly driven quantum medium.
    Author: Erukhimova M, Tokman M.
    Journal: Opt Lett; 2015 Jun 15; 40(12):2739-42. PubMed ID: 26076250.
    Abstract:
    Noise associated with the spontaneous emission in a coherently driven medium is calculated. The significant field-induced modification of relation between the noise power and damping constant in a thermal reservoir is obtained. The nonlinear noise exchange between different atomic frequencies leads to violation of standard relations dictated by the fluctuation-dissipation theorem. The developed general method is applied to the EIT system, attractive for realization of different quantum-information processing devices. It is shown that there is a significant factor defining the thermal noise at operating frequency in the EIT system. It is the averaged number of thermal photons at low frequency of ground state splitting.
