| Abstract: | The effects of dissipative dynamics on the magnitude of entanglement generated In atom-photon interactions inside cavities
is studied. We present some concrete examples of environment Induced entanglement in alom-photon interactions. We consider
various dissipative atom-cavity systems and show that their collective dynamics can be used to maximize entanglement for intermediate
values of the cavity leakage parameter κ. We first consider the interaction of a single two-level atom with one of two coupled
microwave cavities and show analytically that the atom-cavity entanglement increases with cavity leakage. We next consider
a system of two atoms passing successively through a cavity and derive the expression for the maximum value of in terms of
the Rabi angle gt, for which the two-atom entanglement can be Increased. Finally, numerical investigation of micromaser dynamics also reveals
the increase of two-atom entanglement with stronger cavity-environment coupling for experimentally attainable values of the
micromaser parameters. |
