16 Sep 2002 | Subject: | Mathematical Physics MSC-class: 81U99 | math-ph math.MP | Abstract: | We introduce a mathematical setup for charge transport in quantum pump connected to a number of external leads. It is proved that under rather general assumption on the Hamiltonian describing the system, in the adiabatic limit, the current through the pump is given by a formula of Buttiker, Pretre, and Thomas, relating it to the frozen S-matrix and its time derivative. | Source: | arXiv, math-ph/0209029 | Services: | Forum | Review | PDF | Favorites |
