Spectrum generating algebra for the continuous spectrum of a free particle in Lobachevski space
M. Gadella, J. Negro, G. P. Pronko +1
In this paper, we construct a Spectrum Generating Algebra (SGA) for a quantum system with purely continuous spectrum: the quantum free particle in a Lobachevski space with constant…
On the Various Aspects of Hamiltonian Description of the Mechanics of Continuous Media
G. Pronko
We consider a general approach to the theory of continuous media starting from Lagrangian formalism. This formalism which uses the trajectories if constituents of media is very con…
Classical and quantum integrability in 3D systems
M. Gadella, J. Negro, G. P. Pronko +1
In this contribution, we discuss three situations in which complete integrability of a three dimensional classical system and its quantum version can be achieved under some conditi…
Possible nature of
S. S. Gershtein, A. K. Likhoded, G. P. Pronko
We discuss exotic states X(3872) and , observed recently in experiment Belle. The QCD-string based explanation is suggested.
Kepler Problem in the Constant Curvature Space
G. Pronko
We present algebraic derivation of the result of Schrödinger [1] for the spectrum of hydrogen atom in the space with constant curvature.
Quantum superintegrable system for arbitrary spin
G. Pronko
In [1] was considered the superintegrable system which describes the magnetic dipole with spin 1/2 (neutron) in the field of linear current. Here we present its generalization for…
