Annealed and quenched fluctuations for ballistic random walks in random environment on Z
Random walk in random environment stable laws
font style='font-size:12px;'>
2011/1/19
We consider transient random walks in random environment on Z in the positive speed
(ballistic) and critical zero speed regimes. A classical result of Kesten, Kozlov and Spitzer proves that the hitti...
Connectivity properties of random interlacement and intersection of random walks
Random interlacement random walk intersection of random walks capacity

We consider the interlacement Poisson point process on the space of doubly-infinite Zd-valued
trajectories modulo time shift, tending to infinity at positive and negative infinite times. The set of v...

In [Ka], Kaimanovich dened an augmented rooted tree X for the d-dimensional Sierpinski gasket K. Let fZtg be the simple random walk on X,starting at the root ;.
Enumeration of closed random walks in the square lattice according to their areas
Enumeration of closed random square lattice
font style='font-size:12px;'>
2011/2/22
We study the area distribution of closed walks of length n, begin-ning and ending at the origin. The concept of area of a walk in the square lattice is generalized and the usefulness of the new concep...
Poisson--Dirichlet branching random walks
Poisson--Dirichlet random walks
font style='font-size:12px;'>
2011/1/20
We determine, to within O(1), the expected minimal position at level n in certain branching random walks. The walks under consideration have displacement vector (v1; v2; : : :) where each vj is the su...
Tightness for Maxima of Generalized Branching Random Walks
Tightness for Maxima of Generalized Random Walks
font style='font-size:12px;'>
2011/1/18
We study generalized branching random walks, which allow time dependence and local dependence
between siblings. Under appropriate tail assumptions, we prove the tightness of Fn(· −Med(Fn)), whe...
Number variance for hierarchical random walks and related fluctuations

font style='font-size:12px;'>
2010/11/24
We study an infinite system of independent symmetric random walks on a hierarchical group, in particular, the c-random walks. Such walks are used, e.g., in population genetics. The number variance pr...

Let (\rho_\lambda)_{\lambda\in \Lambda} be a holomorphic family of representations of a finitely generated group G into PSL(2,C), parameterized by a complex manifold \Lambda . We define a notion of b...
Concave Majorants of Random Walks and Related Poisson Processes
Concave Majorants Related Poisson Processes
font style='font-size:12px;'>
2010/11/19
We offer a unified approach to the theory of concave majorants of random walks by providing a path transformation for a walk of finite length that leaves the law of the walk unchanged whilst providin...
Upper tails of self-intersection local times of random walks: survey of proof techniques
self-intersection random walks
font style='font-size:12px;'>
2010/11/19
The asymptotics of the probability that the self-intersection local time of a random walk on $\Z^d$ exceeds its expectation by a large amount is a fascinating subject because of its relation to some ...
Conditional and uniform quenched CLTs for one-dimensional random walks among random conductances

2010/11/11
We study a one-dimensional random walk among random conductances, with unbounded jumps. Assuming the ergodicity of the collection of conductances and a few other technical conditions (uniform elliptic...

The extremely fascinating behaviors of the quantum walks of particles, which differ much from the classical counterparts, have attracted many physicists. Here we investigate another interesting part ...

Quantum random walks (QRWs) can be used to perform both quantum simulations and quantum algorithms. In order to exploit this potential, quantum walks on different types of graphs must be physically im...

Consider a system of particles evolving as independent and iden-tically distributed (i.i.d.) random walks. Initial fluctuations in the particle density get translated over time with velocity ~v, the c...
