Abstract
The interaction between planar quasiparticles in a $d_{x^2-y^2}$ superconductor and quantized vortices associated with a magnetic field perpendicular to the plane is shown to induce a pair potential with $d_{xy}$ symmetry, out of phase with the $d_{x^2-y^2}$ order. A microscopic calculation of a process involving quasiparticle scattering by the supercurrent around a vortex and Andreev reflection from its core is presented. Other processes that also lead to an $id_{xy}$ pair potential are discussed. It is argued that such a fully gapped state may be the high-field low temperature phase observed by Krishana and Ong et al. in magnetothermal conductivity measurements of superconducting single-crystal Bi-2212.
