Journal ArticleDOI
Diffusion and Localization in a Dissipative Quantum System
TL;DR: In this article, the motion of a quantum mechanical particle is studied in the presence of a periodic potential and frictional forces, and the behavior changes from diffusion to localization depending on the parameters.
Journal ArticleDOI
Weak localization: The quasiclassical theory of electrons in a random potential
Sudip Chakravarty,Albert Schmid +1 more
TL;DR: In this article, a theory of weak localization which is put rigorously on a quasiclassical basis is presented, and all the important quantitative results obtained so far are recovered.
Journal ArticleDOI
Linearized kinetic equations and relaxation processes of a superconductor near T c
Albert Schmid,Gerd Schön +1 more
TL;DR: In this article, the authors derived a set of linearized equations for the deviation from the equilibrium value of the quasiparticle distribution function as well as of the order parameter, and the equations were solved for the case of an injection of a stationary quaiparticle into a superconductor.
Journal ArticleDOI
A time dependent Ginzburg-Landau equation and its application to the problem of resistivity in the mixed state
TL;DR: In this paper, a time dependent modification of the Ginzburg-Landau equation is given, based on the assumption that the functional derivative of the free energy expression with respect to the wave function is a generalized force in the sense of irreversible thermodynamics acting on the wave functions.
Journal ArticleDOI
On a quasiclassical Langevin equation
TL;DR: In this paper, it was shown that the motion of a quantum mechanical particle coupled to a dissipative environment can be described by a Langevin equation where the stochastic force is generalized such that its power spectrum is in accordance with the fluctuation-dissipation theorem.
