Mean-field dynamics of a Bose Josephson junction in an optical cavity
摘要：
研究了色散耦合到高精细度光腔单模的玻色约瑟夫森结的平均场动力学。导出了玻色约瑟夫森结的有效经典哈密顿量，并从相图的角度研究了其动力学性质。结果表明，强凝聚场耦合确实改变了玻色约瑟夫森结的动力学性质。讨论了相干操纵和用\textsl{in situ}观测玻色约瑟夫森结动力学的可能性。
英文摘要：
We study the mean-field dynamics of a Bose Josephson junction which is dispersively coupled to a single mode of a high-finesse optical cavity. An effective classical Hamiltonian for the Bose Josephson junction is derived and its dynamics is studied in the perspective of phase portrait. It is shown that the strong condensate-field coupling does alter the dynamics of the Bose Josephson junction drastically. The possibility of coherent manipulating and \textsl{in situ} observation of the dynamics of the Bose Josephson junction is discussed.
