Random walks on barycentric subdivisions and the Strichartz hexacarpet
Random walks barycentric subdivisions the Strichartz hexacarpet
2011/7/29
Abstract: We investigate the relation between simple random walks on repeated barycentric subdivisions of a triangle and a self-similar fractal, Strichartz hexacarpet, which we introduce. We explore a...

Abstract: Consider an N-dimensional Markov chain obtained from N one-dimensional random walks by Doob h-transform with the q-Vandermonde determinant. We prove that as N becomes large, these Markov cha...
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 ...
Integrated photonic 3D waveguide arrays for quantum random walks on a circle
Integrated 3D waveguide quantum random circle

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...
Matrix valued Szego polynomials and quantum random walks
Matrix valued Szego polynomials quantum random walks

We consider quantum random walks (QRW) on the integers, a subject that has been considered in the last few years in the framework of quantum computation. We show how the theory of CMV matrices gives a...
Variable Survival Exponents in History-Dependent Random Walks: Hard Movable Reflector
Variable Survival Exponents History-Dependent Random Walks Hard Movable Reflector
2010/10/28
We review recent studies demonstrating a nonuniversal (continuously variable) survival exponent for historydependent random walks, and analyze a new example, the hard movable partial reflector. These ...
