量子热晶体管

Quantum thermal transistor

Karl Joulain, Jérémie Drevillon, Younès Ezzahri, Jose Ordonez-Miranda

摘要:

我们证明了热晶体管可以由3个相互作用的子系统的量子系统组成,每个子系统耦合到一个热库。这种热晶体管类似于电子双极晶体管,其具有控制集电极和发射极处的热流的能力,并在基极处施加热流。这是通过强耦合形式主义确定热通量来实现的。对于3个相互作用的自旋的情况下,其中之一是耦合到其他2,这不是直接耦合,它示出了高放大率可以在很宽的范围内的能量参数和温度。原则上,所提出的量子晶体管可以用于开发纳米系统中的热调制器和热放大器等设备。

英文摘要:

We demonstrate that a thermal transistor can be made up with a quantum system of 3 interacting subsystems , coupled to a thermal reservoir each. This thermal transistor is analogous to an electronic bipolar one with the ability to control the thermal currents at the collector and at the emitter with the imposed thermal current at the base. This is achieved determining the heat fluxes by means of the strong-coupling formalism. For the case of 3 interacting spins, in which one of them is coupled to the other 2, that are not directly coupled, it is shown that high amplification can be obtained in a wide range of energy parameters and temperatures. The proposed quantum transistor could, in principle, be used to develop devices such as a thermal modulator and a thermal amplifier in nano systems.
