论文摘要
我们研究了低能（准）颗粒的传输特性，这些颗粒在弹道上穿越正常和Andreev二维开放式腔，具有西奈质形状。我们考虑了四种不同的几何设置，并专注于转运对应用磁场强度的依赖性。通过求解每个设置的经典运动方程式，我们根据台球的正常版本和Andreev版本的传输和反射系数来计算磁性，在后者中计算出临界场值，该临界场值以高于孔的外向电流为零。
We study the transport properties of low-energy (quasi)particles ballistically traversing normal and Andreev two-dimensional open cavities with a Sinai-billiard shape. We consider four different geometrical setups and focus on the dependence of transport on the strength of an applied magnetic field. By solving the classical equations of motion for each setup we calculate the magnetoconductance in terms of transmission and reflection coefficients for both the normal and Andreev versions of the billiard, calculating in the latter the critical field value above which the outgoing current of holes becomes zero.
