Density of states "width parity" effect in d-wave superconducting quantum wires
K. Ziegler, W. A. Atkinson, P. J. Hirschfeld
We calculate the density of states (DOS) in a clean mesoscopic d-wave superconducting quantum wire, i.e. a sample of infinite length but finite width . For open boundary conditi…
Details of disorder matter in 2D d-wave superconductors
W. A. Atkinson, P. J. Hirschfeld, A. H. MacDonald +1
We demonstrate that discrepancies between predicted low-energy quasiparticle properties in disordered 2D d-wave superconductors occur because of the unanticipated importance of dis…
Reply to the Comment by A.A. Nersesyan and A.M. Tsvelik on the "Non--Zero Fermi Level Density of States for a Disordered d-Wave Superconductor in Two Dimensions" (PRL 77, 3013 (1996)) by K. Ziegler, M.H. Hettler and P.J. Hirschfeld
K. Ziegler, M. H. Hettler, P. J. Hirschfeld
In a recent Comment (cond-mat/9701197) on our Letter (PRL 77, 3013 (1996), cond-mat/9604176) Nersesyan and Tsvelik questioned the relevance of our exact calculation of the density…
Comment on "Nonzero Fermi Level Density of States for a Disordered d-wave superconductor in 2D" by Ziegler et al. PRL 77, 3013 (1996)
A. A. Nersesyan, A. M. Tsvelik
In their paper Ziegler et al. claim that the model of 2D Dirac fermions in a random gauge potential has a finite density of states at zero energy. We point out that the approach us…
Nonzero Fermi Level Density of States for a Disordered d-Wave Superconductor
Klaus Ziegler, Matthias H. Hettler, Peter J. Hirschfeld
It has been known for some time that, in three dimensions, arbitrarily weak disorder in unconventional superconductors with line nodes gives rise to a nonzero residual density of z…
