Abstract We study the quantum description of a neutral particle that has a permanent magnetic dipole moment that interacts with the Aharonov–Casher-type field configuration and a nonuniform magnetic field. From the interaction of the magnetic dipole moment with the magnetic field, an effective scalar potential arises in the Schrodinger–Pauli equation, which is characterized by being spin-dependent and proportional to the inverse of the square of the radial distance. We thus study the analytical solutions to the Schrodinger–Pauli equation for the two cases where the spin-dependent potential can be attractive and repulsive.

存在自旋相关电位时的 Aharonov-Casher 效应

摘要 我们研究了具有永久磁偶极矩的中性粒子的量子描述,该磁偶极矩与 Aharonov-Casher 型场配置和非均匀磁场相互作用。由于磁偶极矩与磁场的相互作用,薛定谔-泡利方程中产生了一个有效的标量势,其特征是与自旋相关并与径向距离的平方的倒数成正比。因此,我们研究了 Schrodinger-Pauli 方程的解析解,适用于自旋相关势可以具有吸引力和排斥性的两种情况。
