چکیده
We study Hamiltonian dynamics of a single two-level atom interacting with two modes in a single cavity, which can also include an optical Kerr nonlinearity. Our model is quite general and is solved analytically and studied numerically, and the model reduces to several well known systems by setting certain parameters in the Hamiltonian to zero. We calculate and discuss entanglement between the tripartite system of one atom and the two cavity modes. PACS: 32.80.-t; 42.50.Ct; 03.65.Ud; 03.65.Yz.

Abstract: In this contribution, we study a single Cooper pair box interacts with a single cavity mode. We show the roles played by the detuning parameters and charged capacities on the degree of entanglement. For large values of the detuning parameter the survival entanglement increases on the expanse of the degree of entanglement. We generate a maximum entangled state and use it to perform the...

We consider a small partially reflecting vibrating mirror coupled dispersively to a single optical mode of a high finesse cavity. We show this arrangement can be used to implement quantum squeezing of the mechanically oscillating mirror.
