Steady-state entanglement of two atoms created by classical driving field
Özgür Çakır, Alexander A. Klyachko, A.S. Shumovsky · Physical Review A · 2005
The stabilization of entanglement caused by action of a classical driving field in the system of two-level atoms with the dipole interaction accompanied by spontaneous emission is discussed. An exact solution shows that the maximum amount of concurrence that can be achieved in the Lamb-Dicke limit is 0.43. Dependence of entanglement on interatomic distance and the classical driving field, beyond the Lamb-Dicke limit, is examined numerically.
