J. E. Avron, A. Elgart, G. M. Graf, L. Sadun, K. Schnee

摘要:

本文介绍了一种外引线连接的量子泵中电荷输运的数学模型。证明了在对描述系统的哈密顿量作相当一般的假设下,在绝热极限下,通过泵的电流由Buttiker,Pretre和Thomas的公式给出,并将其与冻结的S矩阵及其时间导数联系起来。

英文摘要:

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.
