Simultaneous first and second order percolation transitions in interdependent networks
Dong Zhou, Amir Bashan, Reuven Cohen +3
In a system of interdependent networks, an initial failure of nodes invokes a cascade of iterative failures that may lead to a total collapse of the whole system in a form of an ab…
Time averaged Einstein relation and fluctuating diffusivities for the Lévy walk
Daniela Froemberg, Eli Barkai
The Lévy walk model is a stochastic framework of enhanced diffusion with many applications in physics and biology. Here we investigate the time averaged mean squared displacement $…
Mass Dependence of Instabilities of an Oscillator with Multiplicative and Additive Noise
Moshe Gitterman, David A. Kessler
We study the instabilities of a harmonic oscillator subject to additive and dichotomous multiplicative noise, focussing on the dependance of the instability threshold on the mass.…
Fluctuations of noise and the low frequency cutoff paradox
Markus Niemann, Holger Kantz, Eli Barkai
Recent experiments on blinking quantum dots and weak turbulence in liquid crystals reveal the fundamental connection between noise and power law intermittency. The non-statio…
Weak subordination breaking for the quenched trap model
Stas Burov, Eli Barkai
We map the problem of diffusion in the quenched trap model onto a new stochastic process: Brownian motion which is terminated at the coverage "time" ${\cal S}_α=\sum_{x=-\infty} ^\…
Theory of fractional-Lévy kinetics for cold atoms diffusing in optical lattices
David A. Kessler, Eli Barkai
Recently, anomalous superdiffusion of ultra cold 87Rb atoms in an optical lattice has been observed along with a fat-tailed, Lévy type, spatial distribution. The anomalous exponent…
