The Physics of Coupled Atomic-Molecular Condensate System

Abstract

The primary purpose of this proposal is to explore the physics of multi-component condensates containing both atomic and molecular species. The adiabatic condition, which sets the limit to the powers and the widths of the laser pulses for an efficient STIRAP, is studied in connection with the collective excitation modes of the CPT state. The resonant Fermi model in which atoms of two opposite spins are coupled to the Feshbach molecules is studied from a quantum optics perspective by equating it to the single-mode laser cavity model. The same model, when a laser field is applied between the excited and ground molecular states, is shown to be capable of coherent oscillations that stem from the existence of an atom-molecule dark state. The bosonic counterpart of the resonant Fermi model is studied in connection to the subject of phase separation; a rich set of phase separation is shown to exist, including that between two distinct mixed atom-molecule phases, a property quite unique to the heteronuclear model. Matter-wave bistability of the multi-component condensates is explored both with and without the presence of an optical cavity. Also, explored is the possibility of using electromagnetically induced transparency as an alternative to RF spectrum to determine the onset of BCS superfluid.
