两个耦合双量子点系统作为热机的工作物质

Two Coupled Double Quantum Dots Systems as an working substance for Heat Machines

Jefferson Luan D. de Oliveira, Moises Rojas, Cleverson Filgueiras

摘要:

本文提出了一种利用一对耦合双量子点(DQD)作为工作物质的量子热机的概念设计,每个DQD都有一个多余的电子相互作用。我们定义了一个压缩比之间的比例库仑耦合,描述了电子之间的相互作用,在等容过程中的量子奥托循环,然后我们分析了我们的热机器的操作的不同制度的出现。我们还展示了如何实现一个经典的不可想象的奥托引擎,当考虑到由于与每个单独的DQD之间的单个电子的量子隧穿相关的参数的影响。

英文摘要:

This paper presents a conceptual design for quantum heat machines using a pair of coupled double quantum dots (DQDs), each DQD with an excess electron to interact, as an working substance. We define a compression ratio as the ratio between the Coulomb couplings which describes the interaction between the electrons during the isochoric processes of the quantum Otto cycle and then we analyse the arising of different regimes of operations of our thermal machine. We also show how we can achieve a classically inconceivable Otto engine, when considering the effects due to the parameters related to the quantum tunneling of a single electron between each individual DQD.
