Time-reversal symmetry-breaking states near grain boundaries between d -wave superconductors
Year: 1998
Type: article
Abstract: In this paper we study the order parameter and density of states near a grain boundary between two ${d}_{{x}^{2}{\ensuremath{-}y}^{2}}$ superconductors. We examine broken time-reversal symmetry near the interface. In particular we show that, under suitable circumstances, time-reversal symmetry must be broken even when the order parameter is purely ${d}_{{x}^{2}{\ensuremath{-}y}^{2}}$ everywhere in space.
