Thermal entanglement in two atoms with dipole-dipole and Ising interactions

Rodion K Zakharov and Eugene K. Bashkirov, Samara University

Abstract

We investigate the dynamics of a system of two two-level atoms
(qubits) interacting with a single mode radiation field. The two atoms are coupled
to each other through dipole-dipole as well as Ising interactions. Using an exact solution for
the model under cosideration we derived the negativity for different atomics states.
