AI 中文摘要
我们预测了一种新的电子输运的粘手性 regime，其中空间变化的霍尔粘度选择涡旋流动模式。均匀霍尔粘度无法改变不可压缩的体流动，但其空间梯度会重新分配涡度，放大一个腔室中的涡旋，同时抑制另一个腔室中的涡旋。我们进一步确定，潜在机制对于回流是通用的，对器件几何细节不敏感。本文绘制了相应的相图，并表明该 regime 在谷极化双层石墨烯中可通过实验实现。
英文摘要
We predict a new viscochiral regime of electronic transport in which spatially varying Hall viscosity selects vortical flow patterns. Although uniform Hall viscosity cannot alter incompressible bulk flow, its spatial gradient redistributes vorticity, amplifying vortices in one chamber while suppressing the vortex in the other. We further determine the underlying mechanism to be generic to recirculating flows and insensitive to the details of the device geometry. The paper maps the resulting phase diagram and shows that the regime is experimentally accessible in valley-polarized bilayer graphene.
