Irreversibility, Mechanical Entanglement and Thermal Melting in Superconducting Vortex Crystals with Point Impurities
Deniz Ertas, David R. Nelson
We discuss the onset of irreversibility and entanglement of vortex lines in high Tc superconductors due to point disorder and thermal fluctuations using a simplified cage model. A…
Pinning and Tribology of Tethered Monolayers on Disordered Substrates
Carlo Carraro, David R. Nelson
We study the statistical mechanics and dynamics of crystalline films with a fixed internal connectivity on a random substrate. Defect free triangular lattices exhibit a sharp trans…
Electrostriction of Polar Glasses
J. I. Katz, David R. Nelson
We develop a finite temperature theory for the susceptibility and electrostriction of isotropic substances in which permanent electric dipoles are restrained from free rotation by…
Localization transitions in non-Hermitian quantum mechanics
Naomichi Hatano, David R. Nelson
We study the localization transitions which arise in both one and two dimensions when quantum mechanical particles described by a random Schrödinger equation are subjected to a con…
