论文摘要
固态系统中对粘性电子流的明显识别的签名一直是寻找流体动力电子传输行为的重要任务。在这项工作中，我们从理论上研究了流体动力学状态中多发霍尔杆型设备中通用非galian不变的电子液体的非局部电阻和热电阻。该设备不均匀性的作用在与远程相关半径的疾病电位模型中仔细解决了。我们获得了适用于从电荷中立到高电子密度的整个跨界方案中的热电阻力的分析表达式。我们表明，电子流的涡度成分以热传输模式表现在靠近电荷中立性的热传输模式下，在电流中的固有电导率已经抑制了涡度中立。可以通过高分辨率热成像探针测试此行为。
The pursuit for clearly identifiable signatures of viscous electron flow in the solid state systems has been a paramount task in the search of the hydrodynamic electron transport behavior. In this work, we investigate theoretically the nonlocal electric and thermal resistances for the generic non-Galilean-invariant electron liquids in the multiterminal Hall-bar devices in the hydrodynamic regime. The role of the device inhomogeneity is carefully addressed in the model of the disorder potential with the long-range correlation radius. We obtain analytic expressions for the thermoelectric resistances that are applicable in the full crossover regime from charge neutrality to high electron density. We show that the vortical component of the electron flow manifests in the thermal transport mode close to the charge neutrality where vorticity is already suppressed by the intrinsic conductivity in the electric current. This behavior can be tested by the high-resolution thermal imaging probes.
