We review several results related to the problem of a quantum particle in a random environment. In an introductory part, we recall how several functionals of Brownian motion arise in the study of electronic transport in weakly disordered metals (weak localization). Two aspects of the physics of the one-dimensional strong localization are reviewed: some properties of the scattering by a random potential (time delay distribution) and a study of the spectrum of a random potential on a bounded…

Winding statistics of a Brownian particle on a ring
We consider a Brownian particle moving on a ring. We study the probability distributions of the total number of turns and the net number of counter-clockwise turns the particle makes until time t.…
Brownian excursion area, Wright’s constants in graph enumeration, and other Brownian areas
This survey is a collection of various results and formulas by different authors on the areas (integrals) of five related processes, viz. Brownian motion, bridge, excursion, meander and double…
Spectral theory of fluctuations in time-average statistical mechanics of reversible and driven systems
We present a spectral-theoretic approach to time-average statistical mechanics for general, non-equilibrium initial conditions. We consider the statistics of bounded, local additive functionals of…
Quantum oscillations and decoherence due to electron-electron interaction in metallic networks and hollow cylinders
We have studied the quantum oscillations of the conductance for arrays of connected mesoscopic metallic rings, in the presence of an external magnetic field. Several geometries have been considered:…

VIBRATION SPECTRA OF FINITELY RAMIFIED, SYMMETRIC FRACTALS
We show how to calculate the spectrum of the Laplacian operator on fully symmetric, finitely ramified fractals. We consider well-known examples, such as the unit interval and the Sierpinski gasket,…
Vibration modes of 3n-gaskets and other fractals
We rigorously study eigenvalues and eigenfunctions (vibration modes) on the class of self-similar symmetric finitely ramified fractals, which include the Sierpinski gasket and other 3n-gaskets. We…

TLDR
Sinai's model of diffusion in one dimension with random local bias is studied by a real space renormalization group, which yields exact results at long times and rare events corresponding to intermittent splitting of the thermal packet between separated wells which dominate some averaged observables are characterized in detail.
