Low-temperature transition of 2d random-bond Ising model and quantum infinite randomness
Akshat Pandey, Aditya Mahadevan, A. Alan Middleton +1
At low temperatures, the classical two-dimensional random bond Ising model undergoes a frustration-driven ferromagnet-to-paramagnet transition controlled by a zero-temperature fixe…
Depinning with dynamic stress overshoots: Mean field theory
J. M. Schwarz, Daniel S. Fisher
An infinite-range model of an elastic manifold pulled through a random potential by an applied force is analyzed focusing on inertial effects. When the inertial parameter, ,…
Collective Transport: From Superconductors to Earthquakes
D. S. Fisher
In these lectures, a variety of non-equilibrium transport phenomena are introduced that all involve, in some way, elastic manifolds being driven through random media. A simple clas…
Collective Particle Flow through Random Media
Joe Watson, Daniel S. Fisher
A simple model for the nonlinear collective transport of interacting particles in a random medium with strong disorder is introduced and analyzed. A finite threshold for the drivin…
Prospects for Non--Fermi--Liquid Behavior of a Two Level Impurity in a Metal
Aris L. Moustakas, Daniel S. Fisher
It has been claimed that an impurity hopping between two sites in a metal can lead to non--Fermi liquid behavior if the bias between the two sites is tuned to zero. Here it is show…
Interstitials, Vacancies, and Supersolid Order in Vortex Crystals
Erwin Frey, David R. Nelson, Daniel S. Fisher
Interstitials and vacancies in the Abrikosov phase of clean Type II superconductors are line imperfections, which cannot extend across macroscopic equilibrated samples at low tempe…
