Vortex lines in the three-dimensional XY model with random phase shifts
M. S. Li, T. Nattermann, H. Rieger +1
The stability of the ordered phase of the three-dimensional XY-model with random phase shifts is studied by considering the roughening of a single stretched vortex line due to the…
Driven Interface Depinning in a Disordered Medium
Heiko Leschhorn, Thomas Nattermann, Semjon Stepanow +1
The dynamics of a driven interface in a medium with random pinning forces is analyzed. The interface undergoes a depinning transition where the order parameter is the interface vel…
Topological Order in the Vortex Glass Phase of High-Temperature Superconductors
J. Kierfeld, T. Nattermann, T. Hwa
The stability of a vortex glass phase with quasi-long-range positional order is examined for a disordered layered superconductor. The role of topological defects is investigated us…
ABSENCE OF REENTRANCE IN THE TWO-DIMENSIONAL XY-MODEL WITH RANDOM PHASE SHIFT
Thomas NATTERMANN, Stefan SCHEIDL, Sergey E. KORSHUNOV +1
We show, that the 2D XY-model with random phase shifts exhibits for low temperature and small disorder a phase with quasi-long-range order, and that the transition to the disordere…
Disorder-Induced Depinning Transition
Terence Hwa, Thomas Nattermann
The competition in the pinning of a directed polymer by a columnar pin and a background of random point impurities is investigated systematically using the renormalization group me…
