R. A. Pepino, J. Cooper, D. Meiser, D. Z. Anderson, M. J. Holland

摘要:

我们推导了一个量子主方程来处理与多个库相互作用的量子系统。的形式主义是用来调查原子输运跨越各种晶格配置。我们演示了如何实现电子二极管,场效应晶体管,和双极结型晶体管的行为与中性,超冷原子被困在光晶格。的原子电子二极管的情况下提供的电流波动的分析。最后,我们表明,这是可能的,以证明与逻辑门的行为在光晶格。

英文摘要:

We derive a quantum master equation to treat quantum systems interacting with multiple reservoirs. The formalism is used to investigate atomic transport across a variety of lattice configurations. We demonstrate how the behavior of an electronic diode, a field-effect transistor, and a bipolar junction transistor can be realized with neutral, ultracold atoms trapped in optical lattices. An analysis of the current fluctuations is provided for the case of the atomtronic diode. Finally, we show that it is possible to demonstrate AND logic gate behavior in an optical lattice.
