Instability in the quantum restart problem
Ruoyu Yin, Qingyuan Wang, Eli Barkai
Repeatedly-monitored quantum walks with a rate yield discrete-time trajectories which are inherently random. With these paths the first-hitting time with sharp restart is stu…
Reply to Comment on "Large fluctuations for spatial diffusion of cold atoms"
Erez Aghion, David A. Kessler, Eli Barkai
We provide a reply to a comment by I. Goychuk arXiv:1708.04155, version v2 from 27 Aug 2017 (not under active consideration with Phys. Rev. Lett.), on our Letter E. Aghion, D. A. K…
Superdiffusive dispersals impart the geometry of underlying random walks
V. Zaburdaev, I. Fouxon, S. Denisov +1
It is recognised now that a variety of real-life phenomena ranging from diffuson of cold atoms to motion of humans exhibit dispersal faster than normal diffusion. Lévy walks is a m…
Aging Wiener-Khinchin Theorem and Critical Exponents of Noise
N. Leibovich, A. Dechant, E. Lutz +1
The power spectrum of a stationary process may be calculated in terms of the autocorrelation function using the Wiener-Khinchin theorem. We here generalize the Wiener-Khinchin theo…
Random time averaged diffusivities for Lévy walks
D. Froemberg, E. Barkai
We investigate a Lévy-Walk alternating between velocities with opposite sign. The sojourn time probability distribution at large times is a power law lacking its mean or…
Infinite Invariant Density Determines Statistics of Time Averages for Weak Chaos
N. Korabel, E. Barkai
Weakly chaotic non-linear maps with marginal fixed points have an infinite invariant measure. Time averages of integrable and non-integrable observables remain random even in the l…
