Selected topics in random walks in random environment

A Drewitz, AF Ramírez - Topics in percolative and disordered systems, 2014 - Springer
Random walk in random environment (RWRE) is a fundamental model of statistical
mechanics, describing the movement of a particle in a highly disordered and …

Convergence of random walks with Markovian cookie stacks to Brownian motion perturbed at extrema

E Kosygina, T Mountford, J Peterson - Probability theory and related fields, 2022 - Springer
We consider one-dimensional excited random walks (ERWs) with iid Markovian cookie
stacks in the non-boundary recurrent regime. We prove that under diffusive scaling such an …

Excited random walk with periodic cookies

G Kozma, T Orenshtein, I Shinkar - 2016 - projecteuclid.org
In this paper we consider an excited random walk (ERW) on Z in identically piled periodic
environment. This is a discrete time process on Z defined by parameters …

Excited random walks with Markovian cookie stacks

E Kosygina, J Peterson - 2017 - projecteuclid.org
We consider a nearest-neighbor random walk on Z whose probability x(j) to jump to the right
from site x depends not only on x but also on the number of prior visits j to x. The collection …

Functional limit laws for recurrent excited random walks with periodic cookie stacks

E Kosygina, J Peterson - 2016 - projecteuclid.org
We consider one-dimensional excited random walks (ERWs) with periodic cookie stacks in
the recurrent regime. We prove functional limit theorems for these walks which extend the …

[HTML][HTML] Strong transience for one-dimensional Markov chains with asymptotically zero drifts

CH Lo, MV Menshikov, AR Wade - Stochastic Processes and their …, 2024 - Elsevier
For near-critical, transient Markov chains on the non-negative integers in the Lamperti
regime, where the mean drift at x decays as 1/x as x→∞, we quantify degree of transience …

[HTML][HTML] Excited mob

G Amir, T Orenshtein - Stochastic Processes and their Applications, 2016 - Elsevier
We study one dimensional excited random walks (ERW) on iterated leftover environments.
We prove a 0–1 law for directional transience and a law of large numbers for such …

Monotonicity and regularity of the speed for excited random walks in higher dimensions

CD Pham - 2015 - projecteuclid.org
We introduce a method for studying monotonicity of the speed of excited random walks in
high dimensions, based on a formula for the speed obtained via cut-times and Girsanov's …

Excursions and occupation times of critical excited random walks

D Dolgopyat, E Kosygina - arXiv preprint arXiv:1410.7090, 2014 - arxiv.org
The paper considers excited random walks (ERWs) on integers in iid environments with a
bounded number of excitations per site. The emphasis is primarily on the critical case for the …

Excited random walk in a Markovian environment

NF Travers - 2018 - projecteuclid.org
One dimensional excited random walk has been extensively studied for bounded, iid cookie
environments. In this case, many important properties of the walk including transience or …
