摘要

摘要研究了载流子在石墨烯中被恒定梯度磁场禁锢的可能性。获得的结果与地球地磁尾部磁中性片内等离子体运动的经典描述进行了比较。研究采用了原始的严格量规不变方法，利用了额外的运动积分，即所谓的 "伪动量"。揭示了区分量子情况和经典行为的隧道效应的重要作用。

Graphene in the Magnetic Field with Constant Gradient

Abstract

The possibility of the carriers’ confinement in graphene by the magnetic field with constant gradient is considered. The obtained results are compared with the classical description of the plasma motion within magnetically neutral sheet in the earth geomagnetic tail. The consideration is carried out within the original strictly gauge invariant approach making use of the additional integral of motion, so called pseudo-momentum. The essential role of the tunneling effect distinguishing quantum case from classical behavior is revealed.
