Distribution of dynamical quantities in the contact process, random walks, and quantum spin chains in random environments.
We study the distribution of dynamical quantities in various one-dimensional disordered models, the critical behavior of which is described by an infinite randomness fixed point. In the disordered contact process, the survival probability P(t) is found to show multiscaling in the critical point, meaning that P(t)=t-δ, where the (environment and time-dependent) exponent δ has a universal limit d...
متن کاملA PRELUDE TO THE THEORY OF RANDOM WALKS IN RANDOM ENVIRONMENTS
A random walk on a lattice is one of the most fundamental models in probability theory. When the random walk is inhomogenous and its inhomogeniety comes from an ergodic stationary process, the walk is called a random walk in a random environment (RWRE). The basic questions such as the law of large numbers (LLN), the central limit theorem (CLT), and the large deviation principle (LDP) are ...
متن کاملRandom Walks in Random Environments
Random walks provide a simple conventional model to describe various transport processes, for example propagation of heat or diffusion of matter through a medium (for a general reference see, e.g., Hughes (1995)). However, in many practical cases the medium where the system evolves is highly irregular, due to factors such as defects, impurities, fluctuations etc. It is natural to model such irr...
متن کاملRandom Walks in Random Environments
Random walks in random environments (RWRE’s) and their diffusion analogues have been a source of surprising phenomena and challenging problems, especially in the non-reversible situation, since they began to be studied in the 70’s. We review the model, available results and techniques, and point out several gaps in the understanding of these processes. 2000 Mathematics Subject Classification: 6...
