论文摘要
我们表明，携带电流相干电子导体可以视为有效的骨能储存液，涉及不同类型的电子孔对激发。对于弱电子玻色子耦合，可以用陆地台样公式来描述非平衡电子和玻色子之间的杂化能传输。这允许在混合电子玻璃系统中统一说明各种热传输问题。作为应用，我们研究了电子和玻色子之间的非转录热传输，来自玻色子的冷点和电子冷却的热电电流。我们的统一框架提供了一种直观的方式，可以理解电子和玻色子之间的混合能量传输。它打开了非平衡储层工程的方式，以在纳米级不同的准粒子之间有效地控制能量。
We show that a current-carrying coherent electron conductor can be treated as effective bosonic energy reservoir involving different types of electron-hole pair excitation. For weak electron-boson coupling, hybrid energy transport between nonequilibrium electrons and bosons can be described by a Landauer-like formula. This allows for unified account of a variety of heat transport problems in hybrid electron-boson systems. As applications, we study the non-reciprocal heat transport between electrons and bosons, thermoelectric current from a cold-spot and electronic cooling of the bosons. Our unified framework provides an intuitive way of understanding hybrid energy transport between electrons and bosons. It opens the way of nonequilibrium reservoir engineering for efficient energy control between different quasi-particles in the nanoscale.
