Ultracold two-level atom in a quadratic potential
arXiv:1412.5493 · doi:10.1016/j.optcom.2015.03.048
Abstract
We use a right unitary decomposition to study an ultracold two-level atom interacting with a quantum field. We show that such a right unitary approach simplifies the numerical evolution for arbitrary position-dependent atom-field couplings. In particular, we provide a closed form, analytic time evolution operator for atom-field couplings with quadratic dependence on the position of the atom.
