超相对论费米子的弱反定域
Weak antilocalization of ultrarelativistic fermions
摘要：
本文讨论了Berry相位对超相对论粒子在随机介质中绝热后向散射弱局域化现象的影响。我们证明了，玻色子通过一个特定的封闭路径，在相反的方向总是回来的相位（一个例子：后向散射增强的电磁波），而费米子正好在反相。这就产生了一个超相对论费米子的“完全弱反定域”：背散射场强度消失。
英文摘要：
The paper discusses the Berry phase influence on the weak localization phenomenon at the adiabatic backscattering of ultrarelativistic particles in a random medium. We demonstrate that bosons that pass along a certain closed path in opposite directions come back always in phase (an example: the backscattering enhancement of electromagnetic waves), whereas fermions come exactly in antiphase. This produces a "complete weak antilocalization" of ultrarelativistic fermions: the backscattering field intensity vanishes.
