Quantum walk in stochastic environment
Ben Avnit, Doron Cohen
We consider a quantized version of the Sinai-Derrida model for "random walk in random environment". The model is defined in terms of a Lindblad master equation. For a ring geometry…
Quantum irreversibility of quasistatic protocols for finite-size quantized systems
Yehoshua Winsten, Doron Cohen
Quantum mechanically, a driving process is expected to be reversible in the quasistatic limit, also known as the adiabatic theorem. This statement stands in opposition to classical…
Semiclassical theory of strong localization for quantum thermalization
Christine Khripkov, Amichay Vardi, Doron Cohen
We introduce a semiclassical theory for strong localization that may arise in the context of many-body thermalization. As a minimal model for thermalization we consider a few-site…
Path integral approach to the quantum fidelity amplitude
Jiri Vanicek, Doron Cohen
The Loschmidt echo is a measure of quantum irreversibility and is determined by the fidelity amplitude of an imperfect time-reversal protocol. Fidelity amplitude plays an important…
Multiple path adiabatic crossing in a 3 site ring
Dotan Davidovich, Doron Cohen
We find an exact expression for the current that is induced in a 3 site ring during a multiple-path adiabatic crossing. The understanding of the dynamics requires to go beyond the…
Multiple path transport in quantum networks
Geva Arwas, Doron Cohen
We find an exact expression for the current () that flows via a tagged bond from a site ("dot") whose potential () is varied in time. We show that the analysis reduces to tha…
