Non-commutative integration method and generalized coherent states

A. I. Breev, D. M. Gitman

The relationship between states obtained by the non-commutative integration method of the Schrödinger equation on Lie groups and generalized coherent states is investigated. It is…

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…

Coherent states of an accelerated particle

A. I. Breev, D. M. Gitman, Paulo A. Derolle

We construct generalized coherent states (GCS) of a massive accelerated particle. This example is an important step in studying coherent states (CS) for systems with an unbounded m…

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…

Electromagnetic radiation of accelerated charged particle in the framework of a semiclassical approach

T. C. Adorno, A. I. Breev, A. J. D. Farias +1

We address the problem of the electromagnetic radiation produced by charge distributions in the framework of a semiclassical approach proposed in the work by Bagrov, Gitman, Shishm…

Calculation of the wave functions of a quantum asymmetric top using the noncommutative integration method

A. I. Breev, D. M. Gitman

In this work, using the noncommutative integration method of linear differential equations, we obtain a complete set of solutions to the Schrodinger equation for a quantum asymmetr…
