The Gross-Pitaevskii equations and beyond for inhomogeneous condensed bosons
G. G. N. Angilella, S. Bartalini, F. S. Cataliotti +3
A simple derivation of the static Gross-Pitaevskii (GP) equation is given from an energy variational principle. The result is then generalized heuristically to the time-dependent G…
A Proposal for an Optical Implementation of an Universal Quantum Phase Gate
S. Rebic, D. Vitali, C. Ottaviani +4
Large optical nonlinearities occurring in a coherently prepared atomic system are shown to produce phase shifts of order . Such an effect may be observed in ultracold rubidium a…
Quantum theory of a polarization phase-gate in an atomic tripod configuration
S. Rebic, D. Vitali, C. Ottaviani +4
We present the quantum theory of a polarization phase-gate that can be realized in a sample of ultracold rubidium atoms driven into a tripod configuration. The main advantages of t…
