Uniformity transition for ray intensities in random media [PDF]

, 2017
This paper analyses a model for the intensity of distribution for rays propagating without absorption in a random medium. The random medium is modelled as a dynamical map. After N iterations, the intensity is modelled as a sum S of N contributions from

Effects of localization and amplification on distribution of intensity transmitted through random media [PDF]

, 2004
We numerically study the statistical distribution of intensity transmitted through quasi-one dimensional random media by varying the dimensionless conductance $g$ and the amount of absorption or gain.

Discrete-Time Semi-Markov Random Evolutions in Asymptotic Reduced Random Media with Applications

Mathematics, 2020
This paper deals with discrete-time semi-Markov random evolutions (DTSMRE) in reduced random media. The reduction can be done for ergodic and non ergodic media.

Gaussian random waves in elastic media

, 2007
Similar to the Berry conjecture of quantum chaos we consider elastic analogue which incorporates longitudinal and transverse elastic displacements with corresponding wave vectors.

Random walks in disordered lattice, CTRW, memory and dipole transport [PDF]

Magnetic Resonance in Solids, 2017
Application of CTRW (continuous time random walks) to dipole hopping transport is reviewed. Conditions of applicability of basic kinetic equations to spin systems are indicated.

Stiff directed lines in random media

, 2013
We investigate the localization of stiff directed lines with bending energy by a short-range random potential. We apply perturbative arguments, Flory scaling arguments, a variational replica calculation, and functional renormalization to show that a ...

Speed of light in random media [PDF]

Physical Review B, 1992
We give a microscopic derivation of the speed of light relevant for energy transport in media containing randomly distributed scatterers. A comparison is made with the concept of ``mass enhancement'' in electron transport theory. The consequences for the Thouless criterion for strong localization are discussed.

Effect of Dependent Scattering on Light Absorption in Highly Scattering Random Media

, 2017
The approximate nature of radiative transfer equation (RTE) leads to a bunch of considerations on the effect of "dependent scattering" in random media, especially particulate media composed of discrete scatterers, in the last a few decades, which usually

Free energy fluctuations for directed polymers in random media in 1+1 dimension [PDF]

, 2012
We consider two models for directed polymers in space-time independent random media (the O'Connell-Yor semi-discrete directed polymer and the continuum directed random polymer) at positive temperature and prove their KPZ universality via asymptotic ...
