Dissipative Dynamics of a Josephson Junction In the Bose-Gases
arXiv:cond-mat/0207565 · doi:10.1103/PhysRevA.67.013611
Abstract
The dissipative dynamics of a Josephson junction in the Bose-gases is considered within the framework of the model of a tunneling Hamiltonian. The effective action which describes the dynamics of the phase difference across the junction is derived using functional integration method. The dynamic equation obtained for the phase difference across the junction is analyzed for the finite temperatures in the low frequency limit involving the radiation terms. The asymmetric case of the Bose-gases with the different order parameters is calculated as well.
