Time transformation for random walks in the quenched trap model
S. Burov, E. Barkai
Diffusion in the quenched trap model is investigated with an approach we call weak subordination breaking. We map the problem onto Brownian motion and show that the operational tim…
Disorder induced superconducting ratchet effect in nanowires
Shachaf Poran, Efrat Shimshoni, Aviad Frydman
A dc voltage drop develops along amorphous indium oxide nanowires that are exposed to an ac bias source. This voltage is anti-symmetric with magnetic field and is characterized by…
Manipulating Multistage Interconnection Networks Using Fundamental Arrangements
Eran Gur, Zeev Zalevsky
Optimizing interconnection networks is a prime object in switching schemes. In this work the authors present a novel approach for obtaining a required channel arrangement in a mult…
Quantum structural phase transition in chains of interacting atoms
Efrat Shimshoni, Giovanna Morigi, Shmuel Fishman
A quasi one--dimensional system of trapped, repulsively interacting atoms (e.g., an ion chain) exhibits a structural phase transition from a linear chain to a zigzag structure, tun…
Frequency splitting of intervalley phonons in graphene
K. Ziegler, E. Kogan
We study the thermal distribution of intervalley phonons in a graphene sheet. These phonons have two components with the same frequency. The degeneracy of the two modes is preserve…
Synchronization of unidirectional time delay chaotic networks and the greatest common divisor
I. Kanter, M. Zigzag, A. Englert +2
We present the interplay between synchronization of unidirectional coupled chaotic nodes with heterogeneous delays and the greatest common divisor (GCD) of loops composing the orie…
