Theory of equilibrium flux lattices in unconventional superconductors

Abstract

We investigate equilibrium flux lattice structures in superconductors with unconventional order parameters, such as high-$T_c$ cuprates, using a generalized London model with non-local electrodynamics derived from a simple microscopic model. We find a rich phase diagram containing triangular, centered rectangular and square lattices with various orientations to the ionic lattice, as a function of magnetic field and temperature.
