Geometric Meissner Effect in Chiral Superconductors

A recently identified phenomenon namely a Meissner effect induced by curvature has been investigated in a microscopic lattice model of a chiral superconductor. Preliminary numerical results support the picture given earlier in Phys. Rev. Lett. 120, 217002, which was based on an effective mean-field theory. The geometric Meissner effect has been proposed as a smoking gun evidence for chiral superconductivity, and the long term goal of this work is to tie this effect more closely to more realistic microscopic models.
