objectives:
The heat exchange resulting from the coupling between the electrons and the photons in mesoscopic structures was recently measured in the Low Temperature Laboratory. We aim to construct a microscopic theory for this coupling in mesoscopic structures, and especially study the nonequilibrium effects on this coupling. General emphasis will be devoted to the role of the counting statistics of both electrons and the photons. The previous has the role of the counting statistics of both electrons and the photons. The previous has been recently studied in our group, whereas Henning Schomerus is an expert in the latter.
achievements:
Henning Schomerus visited the LTL in November 2006. During this visit, we started a collaboration to study the electron-photon coupling in nanostructures driven out of equilibrium. In this case, the shot noise acts as a means for this coupling. Based on this project, we have submitted a paper T. Ojanen and T. T. Heikkilä, "Photon heat transport in low-dimensional nanostructures" [cond-mat/0701334]. We benefited a lot from the discussions with Henning Schomerus while finishing this paper.
