Coherent states of finite-level systems
A. I. Breev, D. M. Gitman
A method for constructing coherent states (CS) of finite-level systems with a given angular momentum is proposed. To this end we generalize the known spin equation (SE) to an infin…

Resonant entanglement of photon beams by a magnetic field
A. I. Breev, D. M. Gitman
In spite of the fact that photons do not interact with an external magnetic field, the latter field may indirectly affect photons in the presence of a charged environment. This ope…

Light beam interacting with electron medium. Exact solutions of the model and their possible applications to photon entanglement problem
A. I. Breev, D. M. Gitman
We consider a model for describing a QED system consisting of a photon beam interacting with quantized charged spinless particles. We restrict ourselves by a photon beam that consi…
