Railway switch transport model [PDF]
We propose a simple model of coupled heat and particle transport based on a zero-dimensional classical deterministic dynamics which is reminiscent of a railway switch whose action is only a function of the particle's energy. It is shown that already in the minimal three-terminal model, where the second terminal is considered as a probe with zero net ...
