Exact solutions of an extended Dicke model
Exact solutions of the Dicke Hamiltonian plus a dipole-dipole interaction among N two-level atoms are derived based on an algebraic Bethe ansatz. As an example application, the role of the dipole-dipole interaction in ground-state-atom condensates of a system is explored. © 2005 Elsevier B.V. All rights reserved.
