The magnetic susceptibility of the t-J model at low hole doping
D. B. Bailey, A. M. Tikofsky, R. B. Laughlin
We compute the dynamical magnetic susceptibility of the t-J model in its commensurate flux phase at low hole doping. We compare the calculations with experiments and exact diagonal…
Fractional vortices on grain boundaries --- the case for broken time reversal symmetry in high temperature superconductors
D. Bailey, M. Sigrist, R. B. Laughlin
We discuss the problem of broken time reversal symmetry near grain boundaries in a d-wave superconductor based on a Ginzburg-Landau theory. It is shown that such a state can lead t…
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…
