"Tunneling in the self-trapped regime of a two-well Bose-Einstein condensate." PHYSICAL REVIEW A, Volume 90, Issue 5, pp. ? - ?

We find closed-form approximations to the tunneling frequency more accurate than those previously obtained using different techniques. We discuss the central role that tunneling in the self-trapped regime plays in a quantitatively accurate model of a dissipative dimer leaking atoms to the environment. Finally, we describe the prospects of experimental observation of tunneling in the self-trapped regime, both with and without dissipation.11 p.en-USScience & technologyPhysical sciencesOpticsPhysics, atomic, molecular & chemicalDouble-wellQuantum dynamicsInterferometryLimitEntanglementOscillationsBosonsStatesGasesSpinsMathematical sciencesChemical sciencesGeneral physicsArticle10.1103/PhysRevA.90.05361039163
