Entanglement properties in the Inhomogeneous Tavis-Cummings model

Departamento de F´isica, Universidad de Santiago de Chile, Casilla 307 Correo 2, Santiago, Chile(Dated: February 1, 2008)In this work we study the properties of the atomic entanglement in the eigenstates spectrum of theinhomogeneous Tavis-Cummings Model. The inhomogeneity is present in the coupling among theatoms with quantum electromagnetic field. We calculate analytical expressions for the concurrenceand we found that this exhibits a strong dependence on the inhomogeneity.
