受驱动RLC网络的随机和量子热力学

Stochastic and Quantum Thermodynamics of Driven RLC Networks

Nahuel Freitas, Jean-Charles Delvenne, Massimiliano Esposito

摘要:

我们开发了一个一般的随机RLC电网络的热力学建立在工程师常用的动态图形理论表示的顶部。该网络是:开路,因为它包含电阻器以及电流和电压源;非等温,因为电阻器可能处于不同的温度;以及驱动,因为电路元件可能受到外部参数驱动。正确描述每个电阻器中的散热量需要在白噪声理想化范围内谨慎,因为它取决于网络拓扑结构。我们的理论提供了设计基于电路的热机的基础,我们通过使用简单的驱动电路设计冰箱来说明。我们还得到精确的结果,在低温制度中,必须考虑到的量子性质的电噪声。我们这样做,使用半经典的方法,可以证明,以符合一个完全量子处理的线性电路的正则量子化是可能的。我们用它来推广的Landauer-Buttiker公式的能量流到任意时间相关的驱动协议。

英文摘要:

We develop a general stochastic thermodynamics of RLC electrical networks built on top of a graph-theoretical representation of the dynamics commonly used by engineers. The network is: open, as it contains resistors and current and voltage sources, nonisothermal as resistors may be at different temperatures, and driven, as circuit elements may be subjected to external parametric driving. The proper description of the heat dissipated in each resistor requires care within the white noise idealization as it depends on the network topology. Our theory provides the basis to design circuits-based thermal machines, as we illustrate by designing a refrigerator using a simple driven circuit. We also derive exact results for the low temperature regime in which the quantum nature of the electrical noise must be taken into account. We do so using a semiclassical approach which can be shown to coincide with a fully quantum treatment of linear circuits for which canonical quantization is possible. We use it to generalize the Landauer-Buttiker formula for energy currents to arbitrary time-dependent driving protocols.
