Description

Nanoscale machines are strongly influenced by thermal fluctuations, contrary to their macroscopic counterparts. As a consequence, we need to talk about efficiency distributions and not just an average efficiency. Can such a distribution have any universal properties? In earlier work, it was shown, for a particular class of non-equilibrium systems, that, in the large time limit, this distribution always has a "universal" shape. In recent work, we have shown that if we extend this class of systems, the efficiency distribution can be one of several types. We are able to classify when and how these different types occur as well as the exact form of the efficiency distribution in each case. Joint work with Sreekanth K Manikandan, Lennart Dabelow and Ralf Eichhorn
