Gapless Time-Reversal Symmetry Breaking Superconductivity

A. M. Tikofsky, D. B. Bailey

We consider a layered superconductor with a complex order parameter whose phase switches sign from one layer to the next. This system is shown to exhibit gapless superconductivity…

Fractional Vortices as Evidence of Time-Reversal Symmetry Breaking in High-Temperature Superconductors

M. Sigrist, D. B. Bailey, R. B. Laughlin

We argue that recent experiments by Kirtley et al. may show evidence of time reversal symmetry breaking in YBCO at crystal grain boundaries. We illustrate this through a Ginzburg-L…
