Control of atomic entanglement by dynamic Stark effect

Biplab Ghosh, A. S. Majumdar, N. Nayak

We study the entanglement properties of two three-level Rydberg atoms passing through a single-mode cavity. The interaction of an atom with the cavity field allows the atom to make…

Environment assisted entanglement enhancement

Biplab Ghosh, A. S. Majumdar, N. Nayak

We consider dissipative atom-cavity systems and show that their collective dynamics leads to the maximization of entanglement for intermediate values of the cavity leakage paramete…

Atomic entanglement mediated by a squeezed cavity field

Biplab Ghosh, A. S. Majumdar, N. Nayak

We consider the coherent state radiation field inside a micromaser cavity and study the entanglement mediated by it on a pair of two level atoms passing though the cavity one after…

Effects of cavity-field statistics on atomic entanglement in the Jaynes-Cummings model

Biplab Ghosh, A. S. Majumdar, N. Nayak

We study the entanglement properties of a pair of two-level atoms going through a cavity one after another. The initial joint state of two successive atoms that enter the cavity is…

Information transfer in leaky atom-cavity systems

Biplab Ghosh, A. S. Majumdar, N. Nayak

We consider first a system of two enatangled cavities and a single two-level atom passing through one of them. A ``monogamy'' inequality for this tripartite system is quantitativel…

Information transfer through a one-atom micromaser

Animesh Datta, Biplab Ghosh, A. S. Majumdar +1

We consider a realistic model for the one-atom micromaser consisting of a cavity maintained in a steady state by the streaming of two-level Rydberg atoms passing one at a time thro…
