Quantum Systems with Hidden Symmetry. Interbasis Expansions
L. G. Mardoyan, G. S. Pogosyan, A. N. Sissakian +1
This monograph is the English version of the book "Quantum systems with hidden symmetry. Interbasis expansions" published in 2006 by the publishing house FIZMATLIT (Moscow) in Russ…
Some peculiarities in response on filling up the Fermi sphere by quarks
S. V. Molodtsov, G. M. Zinovjev
Considering quarks as the quasi-particles of the model Hamiltonian with four-fermion interaction we study response on the process of filling up the Fermi sphere by quarks.
Path Integral Approach for Superintegrable Potentials on Spaces of Non-constant Curvature: II. Darboux Spaces DIII and DIV
Christian Grosche, George Pogosyan, Alexei Sissakian
This is the second paper on the path integral approach of superintegrable systems on Darboux spaces, spaces of non-constant curvature. We analyze in the spaces $\DIII$ and $\DIV$ f…
Path Integral Approach for Superintegrable Potentials on Spaces of Non-constant Curvature: I. Darboux Spaces DI and DII
Christian Grosche, George S. Pogosyan, Alexei N. Sissakian
In this paper the Feynman path integral technique is applied for superintegrable potentials on two-dimensional spaces of non-constant curvature: these spaces are Darboux spaces D_I…
On a Generalized D-Dimensional Oscillator: Interbasis Expansions
Ye. M. Hakobyan, G. S. Pogosyan, A. N. Sissakian
This article deals with nonrelativistic study of a D-dimensional superintegrable system, which generalizes the ordinary isotropic oscillator system. The coefficients for the expans…
Hidden Symmetry of the Yang--Coulomb System
L. G. Mardoyan, A. N. Sissakian, V. M. Ter--Antonyan
The bound system composed of the Yang monopole coupled to a particle of the isospin by the SU(2) and Coulomb interaction is considered. The generalized Runge--Lenz vector and the S…
