Quantum Theory of Generation of Coherent X-Ray in a Wiggler
H. K. Avetissian, T. R. Hovhannisyan, G. F. Mkrtchian
In this paper we present the nonlinear quantum theory of X-Ray FEL in a wiggler. We present the solution of the Dirac equation in a space periodic strong magnetic field, which desc…
Relativistic Quantum Theory of Cyclotron Resonance in a Medium
H. K. Avetissian, G. F. Mkrtchian, M. G. Poghosyan
In this paper the relativistic quantum theory of cyclotron resonance in an arbitrary medium is presented. The quantum equation of motion for charged particle in the field of plane…
Multiphoton Resonant Transitions of Electrons in the Laser Field in a Medium
H. K. Avetissian, A. L. Khachatryan, G. F. Mkrtchian
Within the scope of the relativistic quantum theory for electron-laser interaction in a medium and using the resonant approximation for the two degenerated states of an electron in…
Relativistic theory of the above-threshold multiphoton ionization of hydrogen-like atoms in the ultrastrong laser fields
H. K. Avetissian, A. G. Markossian, G. F. Mkrtchian
The relativistic theory of above-threshold ionization (ATI) of hydrogen-like atoms in ultrastrong radiation fields, taking into account the photoelectron induced rescattering in th…
