The decay of supercurrent in a 2-d superconductor through the homogeneous quantum nucleation of vortex-antivortex pairs is formulated as a (2 + 1)-d scalar quantum electrodynamic problem. The calculation of the quantum decay rate can then be simplified to the usual single particle WKB calculation. The authors show explicitly that the homogeneous quantum nucleation of vortex-antivortex pairs is incompatible to the existence of the magnus force in the absence of dissipation, and pint out more complicated nucleation processes needed to be studied by the vortex dynamics method in such case. 9 refs.
