Landau型哈密顿量的绝热电荷输运和Kubo公式

Adiabatic Charge Transport and the Kubo Formula for Landau Type Hamiltonians

Alexander Elgart, Benjamin Schlein

摘要:

研究了零温下受有界势扰动的二维Landau模型中的绝热电荷输运。我们表明,如果费米能级位于一个光谱间隙,然后在绝热极限的累积过剩霍尔输运的线性响应Kubo-Streda公式。证明依赖于Nenciu的扩展,一些广义相空间估计,以及对传播速度的限制。

英文摘要:

The adiabatic charge transport is investigated in a two dimensional Landau model perturbed by a bounded potential at zero temperature. We show that if the Fermi level lies in a spectral gap then in the adiabatic limit the accumulated excess Hall transport is given by the linear response Kubo-Streda formula. The proof relies on the expansion of Nenciu, some generalized phase space estimates, and a bound on the speed of propagation.
