Fractional vortices as evidence of time-reversal symmetry breaking in high-temperature superconductors.
We argue that recent experiments by Kirtley et al. [1] may show evidence of time reversal symmetry breaking in YBa2Cu3O7 at crystal grain boundaries. We illustrate this through a Ginzburg-Landau model calculation. Further experimental tests are proposed. 74.20.De, 74.50.+r, 74.72 Typeset using REVTEX 1 In a recent paper, Kirtley et al. [1] reported the observation of magnetic defects at artific...
متن کاملEdge currents in superconductors with a broken time-reversal symmetry.
We analyze edge currents and edge bands at the surface of a time-reversal symmetry breaking dx2-y2 + id(xy) superconductor. We show that the currents have large Friedel oscillations with two interfering frequencies: square root of 2kF from subgap states, and 2kF from the continuum. The results are based independently on a self-consistent slave-boson mean-field theory for the t-J model on a tria...
متن کاملTunneling Gap as Evidence for Time-Reversal Symmetry Breaking at Surfaces of High-Temperature Superconductors
It is argued that recent Josephson junction and point-contact tunneling experiments, interpreted as intended by their authors, indicate that time-reversal symmetry breaking occurs at surfaces of cuprate superconductors. The variation among experiments and the failure of previous searches to find T -violation are ascribed to disorder and effects of 3-dimensionality. The “anyon” approach to the t...
متن کاملJosephson vortices with fractional flux quanta at YBa2Cu3O7Àx grain boundaries
We report numerical simulations of magnetic flux patterns in asymmetric 45° @001#-tilt grain boundaries in YBa2Cu3O72x superconducting films. The grain boundaries are treated as Josephson junctions with a critical current density j c(x) alternating rapidly along the junctions with a typical length scale which is much less than Josephson penetration depth. We demonstrate the existence of Josephs...
متن کاملSpontaneous magnetization and Hall effect in superconductors with broken time-reversal symmetry
Broken time reversal symmetry (BTRS) in d wave superconductors is studied and is shown to yield current carrying surface states. The corresponding spontaneous magnetization is temperature independent near the critical temperature Tc for weak BTRS, in accord with recent data. The Hall conductance is found to vanish at zero wavevector q and finite frequency ω, however at finite q, ω it has an unu...
