The Dirac equation in an external electromagnetic field: symmetry algebra and exact integration

29 Sep 2015  ·  Breev A. I., Shapovalov A. V. ·

Integration of the Dirac equation with an external electromagnetic field is explored in the framework of the method of separation of variables and of the method of noncommutative integration. We have found a new type of solutions that are not obtained by separation of variables for several external electromagnetic fields... We have considered an example of crossed electric and magnetic fields of a special type for which the Dirac equation admits a nonlocal symmetry operator read more
