A Consistent Treatment of Strong Coupling in Disordered Superconducting Films
Margit Steiner, Robert A Smith
We develop a consistent treatment of disorder effects in strong coupling superconductors. We use two different approaches, starting either from above or below the transition temper…
Statistical properties of localisation--delocalisation transition in one dimension
M. Steiner, Yang Chen, M. Fabrizio +1
We study a one-dimensional model of disordered electrons (also relevant for random spin chains), which exhibits a delocalisation transition at half-filling. Exact probability distr…
Random Mass Dirac Fermions in Doped Spin-Peierls and Spin-Ladder systems: One-Particle Properties and Boundary Effects
M. Steiner, M. Fabrizio, Alexander O. Gogolin
Quasi-one-dimensional spin-Peierls and spin-ladder systems are characterized by a gap in the spin-excitation spectrum, which can be modeled at low energies by that of Dirac fermion…
Non-linear current through a barrier in 1D wires with finite-range interactions
Margit Steiner, Wolfgang Häusler
The transport properties of a tunnel barrier in a one-dimensional wire are investigated at finite voltages and temperatures. We generalize the Luttinger model to account for finite…
The effect of magnetic dipolar interactions on the interchain spin wave dispersion in CsNiF_3
M. Baehr, M. Winkelmann, P. Vorderwisch +3
Inelastic neutron scattering measurements were performed on the ferromagnetic chain system CsNiF_3 in the collinear antiferromagnetic ordered state below T_N = 2.67K. The measured…
