Abstract

The wave function of a free electron in a laser plasma described via Riemannian geometry is derived by solving the Dirac equation in the associated curved space-time. If the laser field vanishes, the wave function naturally reduces to the case in flat space-time.

Abstract

The behavior of a charged particle in a strong-laser plasma is discussed by solving the generally covariant equation of motion for a charged particle. The classical description for the radiation of a charged particle in a strong-laser plasma is given, and the intensity and the radiation power are derived in detail.
