Beyond the Big Jump: A Perturbative Approach to Stretched-Exponential Processes
Alberto Bassanoni, Omer Hamdi
The problem of sums of independent, identically distributed random variables with stretched-exponential tails exhibits a dynamical phase transition and has recently reemerged in th…
Sokoban Random Walk: A Trapping Perspective
Prashant Singh, Eli Barkai, David A Kessler
We study caging/trapping in Sokoban-type models, featuring a random walker moving through a disordered medium of obstacles and capable of pushing some obstacles blocking its path.…
Boundary-Induced Drift and Negative Mobility in Constrained Stochastic Systems
Meitar Goldfarb, Stanislav Burov
We study overdamped stochastic dynamics confined by hard reflecting boundaries and show that the combination of boundary geometry and an anisotropic diffusion tensor generically ge…
Transition in Splitting Probabilities of Quantum Walks
Prashant Singh, David A. Kessler, Eli Barkai
We investigate the splitting probability of a monitored continuous-time quantum walk with two targets and show that, in stark contrast to a classical random walk, it exhibits a non…
Sokoban Random Walk: From Environment Reshaping to Trapping Crossover
Prashant Singh, David A. Kessler, Eli Barkai
We study the dynamics of a Sokoban random walker moving in a disordered medium with obstacle density . In contrast to the classic model of de Gennes with static obstacles that e…
Resonances of recurrence time of monitored quantum walks
Ruoyu Yin, Qingyuan Wang, Sabine Tornow +1
The recurrence time is the time a process first returns to its initial state. Using quantum walks on a graph, the recurrence time is defined through stroboscopic monitoring of the…
