Ground state of the gauge invariant Dicke model: condensation of the photons in non-classical states

N. Q. San, O. D. Skoromnik, A. P. Ulyanenkov +2

We investigate the ground state of two physically motivated modifications of the Dicke model. The first modification corresponds to particles whose phase space contains only two st…

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…

Exact solution for the quantum Rabi model with the term

I. D. Feranchuk, N. Q. San, A. U. Leonau +1

Quantum Rabi model (QRM) is widely used for the analysis of the radiation-matter interaction at the fundamental level in cavity quantum electrodynamics. Typically the QRM Hamiltoni…

Relativistic effective charge model of a multi-electron atom

K. Dzikowski, O. D. Skoromnik, I. D. Feranchuk +2

A relativistic version of the effective charge model for computation of observable characteristics of multi-electron atoms and ions is developed. A complete and orthogonal Dirac hy…

Parametric Mössbauer radiation source

O. D. Skoromnik, I. D. Feranchuk, J. Evers +1

Numerous applications of Mössbauer spectroscopy are related to a unique resolution of absorption spectra of resonant radiation in crystals, when the nucleus absorbs a photon withou…

A generating integral for the matrix elements of the Coulomb Green's function with the Coulomb wave functions

K. Dzikowski, O. D. Skoromnik

We analytically evaluate the generating integral and integral moments $J_{nl}(β, r) =…
