X-ray resonance therapy with parametric X-ray radiation (PXR) for sulfur-containing tumor tissues
N. Q. San, O. D. Skoromnik, A. U. Leonau +2
We investigate the possibility of usage of the parametric X-ray radiation (PXR) for the selective therapy of superficial sulfur-containing tumor tissues. In these tissues, the conc…
Approximating Hamiltonian for Hartree-Fock solutions for nonrelativistic atoms
N. Q. San, O. D. Skoromnik, V. V. Triguk +1
In our work we construct a Hamiltonian, whose eigenstates approximate the solutions of the self-consistent Hartree-Fock equations for nonrelativistic atoms and ions. Its eigenvalue…
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…
Superradiant parametric X-ray emission
I. D. Feranchuk, N. Q. San, O. D. Skoromnik
We compute a spectrum of parametric X-ray radiation (PXR) inside a crystal from a bunch of electrons, which is periodically modulated in density. We consider that the bunch of elec…
Eigenstates of two-level systems in a single-mode quantum field: from quantum Rabi model to -atom Dicke model
A. U. Leonau, N. Q. San, A. P. Ulyanenkov +2
In the present paper we show that the Hamiltonian describing the resonant interaction of two-level systems with a single-mode electromagnetic quantum field in the Coulomb gauge…
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…
