低维器件中的量子搅动

Quantum Stirring in low dimensional devices

Itamar Sela, Doron Cohen

摘要:

通过移动散射体,或者更一般地说,通过将量子泵集成到闭合电路中,可以在费米海中感应出循环电流。该感应电流可以具有与泵的“推动”方向相同或相反的方向。我们利用Kubo-Dirac单极子图像给出了相关几何电导的显式表达式,并阐明了与多路径几何中绝热通过理论的联系。

英文摘要:

A circulating current can be induced in the Fermi sea by displacing a scatterer, or more generally by integrating a quantum pump into a closed circuit. The induced current may have either the same or the opposite sense with respect to the "pushing" direction of the pump. We work out explicit expressions for the associated geometric conductance using the Kubo-Dirac monopoles picture, and illuminate the connection with the theory of adiabatic passage in multiple path geometry.
