| Abstract | : | The voltage curve of the annihilation dynamics of a vortex-antivortex (VAV) pair in a mesoscopic superconductor has been investigated based on the Time Dependent Ginzburg Landau (TDGL) equations. The pair was generated only by the current-induced magnetic field. The influence of the annihilation dynamics of a VAV pair on the voltage curve is studied. As the external current density is passed on the sample, a VAV enters the scene, moves toward the centre of the sample, and finally the pair is annihilated. The position, velocity, and acceleration of the vortex and antivortex were calculated as a function of time. The supercurrent density topology, order parameter topology, and voltage curve were also calculated. The influence of the annihilation dynamics of a VAV pair on the voltage curve is discussed. |
