All-coupling solution for the continuous polaron problem in the Schrödinger representation
I. D. Feranchuk, N. Q. San, O. D. Skoromnik
The solution for the large-radius Fröhlich polaron in the Schrödinger representation of the quantum theory is constructed in the entire range of variation of the coupling constant.…
Radiation induced interaction potential of two qubits strongly coupled with a quantized electromagnetic field
I. D. Feranchuk, N. Q. San, A. U. Leonau +1
We investigate the interaction of two two-level qubits with a single mode quantum field in a cavity without rotating wave approximation and considering that qubits can be located a…
Analytic model of a multi-electron atom
O. D. Skoromnik, I. D. Feranchuk, A. U. Leonau +1
A fully analytical approximation for the observable characteristics of many-electron atoms is developed via a complete and orthonormal hydrogen-like basis with a single-effective c…
Regularization of ultraviolet divergence for a particle interacting with a scalar quantum field
O. D. Skoromnik, I. D. Feranchuk, D. V. Lu +1
When a nonrelativistic particle interacts with a scalar quantum field, the standard perturbation theory leads to a dependence of the energy of its ground state on an undefined para…
Structural information extracted from the diffraction of XFEL fs-pulses in a crystal
A. Leonov, D. Ksenzov, A. Benediktovitch +2
We present a theoretical justification for a method of extracting of supplementary information for the phase retrieval procedure taken from diffraction of fs-pulses from X-ray Free…
Regularization of the vacuum fluctuation energy in quantum electrodynamics
I. D. Feranchuk, S. I. Feranchuk
It is shown that the total energy of the vacuum fluctuations of the electron-positron and electromagnetic fields in the quantum electrodynamics can be equal to zero if the "bare" e…
Justification of the single-mode approximation for a finite-duration laser pulse interacting with an electron
O. D. Skoromnik, I. D. Feranchuk
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…
