Abstract
The AC Josephson effect in the interface between a superconducting dot with dx2-y2 symmetry (d-dot) and its surrounding s-wave superconductor is investigated in the presence of an external magnetic field parallel to the interface. We derive the dynamical equations for the phase difference in this d-dot system for two different shapes of d-dot, i.e., square and triangle. The effect of the d-wave symmetry is incorporated in terms of the orientation-dependent Josephson critical current density. We solve numerically the dynamical equations and clarify the dynamics of vortices with half-flux quantum.
