Goldstone Bosons in Josephson Junctions
arXiv:math-ph/0602062 · doi:10.1088/0305-4470/39/37/001
Abstract
For a microscopic model of a Josephson junction the normal coordinates of the two junction Goldstone bosons are constructed and their dynamical spectrum is computed. The explicit dependence on the phase difference of the two superconductors is calculated.
