A. V. Kuznetsov, A. A. Okrugin

摘要:

用量子场论的标准方法,直接从磁场中Dirac方程的精确解出发,得到了电子在恒定均匀磁场中的精确传播子,它是朗道能级的和。该结果可用于进一步发展的计算技术的量子过程中的外部活性介质,特别是在适度大的场强的条件下,当它是不够的,以考虑只有地面朗道能级的贡献。

英文摘要:

The exact propagator for an electron in a constant uniform magnetic field as the sum over Landau levels is obtained by the direct derivation by standard methods of quantum field theory from exact solutions of the Dirac equation in the magnetic field. The result can be useful for further development of the calculation technique of quantum processes in an external active medium, particularly in the conditions of moderately large field strengths when it is insufficient to take into account only the ground Landau level contribution.
