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…
The Friedrichs-Model with fermion-boson couplings II
O. Civitarese, M. Gadella, G. P. Pronko
In this work we present a formal solution of the extended version of the Friedrichs Model. The Hamiltonian consists of discrete and continuum bosonic states, which are coupled to f…
Classical and quantum three-dimensional integrable systems with axial symmetry
M. Gadella, J. Negro, G. P. Pronko
We study the most general form of a three dimensional classical integrable system with axial symmetry and invariant under the axis reflection. We assume that the three constants of…
