Stochastic modeling of spreading and dissipation in mixed-chaotic systems that are driven quasistatically
Yehoshua Winsten, Doron Cohen
We analyze energy spreading for a system that features mixed chaotic phase-space, whose control parameters (or slow degrees of freedom) vary quasi-statically. For demonstration pur…
Emergence of Sinai Physics in the stochastic motion of passive and active particles
Dekel Shapira, Doron Cohen
A particle that is immersed in a uniform temperature bath performs Brownian diffusion, as discussed by Einstein. But Sinai has realized that in a "random environment" the diffusion…
Quantum stochastic transport along chains
Dekel Shapira, Doron Cohen
The spreading of a particle along a chain, and its relaxation, are central themes in statistical and quantum mechanics. One wonders what are the consequences of the interplay betwe…
Localization due to topological stochastic disorder in active networks
Dekel Shapira, Dganit Meidan, Doron Cohen
An active network is a prototype model in non-equilibrium statistical mechanics. It can represent, for example, a system with particles that have a self-propulsion mechanism. Each…
The lognormal-like statistics of a stochastic squeeze process
Dekel Shapira, Doron Cohen
We analyze the full statistics of a stochastic squeeze process. The model's two parameters are the bare stretching rate~, and the angular diffusion coefficient~. We carry out…
Hidden timescale in the response of harmonically driven chaotic systems
Christine Khripkov, Amichay Vardi, Doron Cohen
Linear response theory relates the response of a system to the power-spectrum of its fluctuations. However, the response to external driving in realistic models exhibits a pronounc…
