    A Coherently driven Degenarate Three-Level Atom
    (Addis Ababa University, 2013-06) Terefe, Yosef; Kassahun, Fesseha (PhD)
    We analyze the squeezing and statistical properties of a degenerate three-level atom coupled to a coherent light and vacuum reservoir. In the other way, employ- ing the Heseinberg and Quantum Langevin equation associated with the normal ordering noise operator, we study the squeezing properties, power spectrum, vari- ance and also calculate the mean photon number of the cavity mode. It turns out that the generated light exhibits squeezing under certain conditions
