Temperature and Voltage Probes Far from Equilibrium

We consider an open system of non-interacting electrons consisting of a small sample connected to several reservoirs and temperature or voltage probes. We study the non-linear system of equations that determines the probe parameters. We show that it has a unique solution, which can be computed with a fast converging iterative algorithm. We illustrate our method with two well-known models: the three-terminal system and the open Aharovov-Bohm interferometer.

Escape behaviour of a quantum particle in a loop coupled to a lead

We consider a one-dimensional loop of circumference $L$ crossed by a constant magnetic flux $Φ$ and connected to an infinite lead with coupling parameter $ε$. Assuming that the initial state $ψ_0$ of the particle is confined inside the loop and evolves freely, we analyse the time evolution of the nonescape probability $P(ψ_0,L,Φ,ε,t)$, which is the probability that the particle will still be inside the loop at some later time $t$.
