Manifestly non-Gaussian fluctuations
in superconductor-normal metal tunnel nanostructures is a title of a new arXiv submission of me and my thrusted Finnish collaborators Matti Laakso and Tero Heikkillä. You can read it here.
In short, the paper is about making a commandable Maxwell daemon in SNS structures. Here is a detailed abstract:
We propose a mesoscopic setup which exhibits strong and manifestly non-Gaussian fluctuations of energy and temperature when suitably driven out of equilibrium. The setup consists of a normal metal island (N) coupled by tunnel junctions (I) to two superconducting leads (S), forming a SINIS structure, and is biased near the threshold voltage for quasiparticle tunneling. The fluctuations can be measured by monitoring the time-dependent electric current through the system, which makes the setup suitable for the realization of feedback schemes which allow to stabilize the temperature to the desired value.
