Авторы: Skoromnik, O. D.; Feranchuk, I. D.
Аннотация: The interaction Hamiltonian of an electron and a quasi-monochromatic pulse of
a strong quantized electromagnetic field is examined. Canonical transformations of the field
variables are found that allow the division of the system’s Hamiltonian in two parts. The
first one describes the interaction between an electron and a single collective mode of the field.
The properties of this mode are defined by the superposition of the modes corresponding to the
pulse wave packet. The second part describes the field fluctuations relatively to the collective
mode. The field intensity, pulse duration and transversal spread are estimated for which a
single-mode approximation can be used for the system’s description.2014-04-10T00:00:00ZA Uniformly Suitable Approximation for the Characteristics of the Electromagnetic Field in the Rabi Quantum ModelLeonau, A.U.Feranchuk, I.D.Skoromnik, O.D.San, N.Q.https://elib.bsu.by:443/handle/123456789/3422882026-02-24T03:45:10Z2020-01-01T00:00:00ZЗаглавие документа: A Uniformly Suitable Approximation for the Characteristics of the Electromagnetic Field in the Rabi Quantum Model

Аннотация: A systematic study is made of the efficiency of a uniformly suitable approximation for describing the Rabi quantum model beyond the rotating wave model. The correlation characteristics of the electromagnetic field in a resonator are calculated and the physical effects owing to the counter-rotating terms in the Hamiltonian are examined.2020-01-01T00:00:00ZКвантовые эффекты в процессах взаимодействия электрона с полем лазерной волныСкоромник, О.Д.Феранчук, И.Д.https://elib.bsu.by:443/handle/123456789/3407212026-01-27T03:46:58Z2015-01-01T00:00:00ZЗаглавие документа: Квантовые эффекты в процессах взаимодействия электрона с полем лазерной волны

Аннотация: We present and study new nontopological soliton solutions in the 𝑈(1) gauged nonlinear 𝑂(3) sigma-model with a symmetry breaking potential in 3+1 dimensional flat space-time. The configurations are endowed with an electric and magnetic field and also carry a nonvanishing angular momentum density. We discuss properties of these solitons and investigate the domains of their existence2025-01-01T00:00:00Z
