P-matrix and J-matrix approaches. Coulomb asymptotics in the harmonic oscillator representation of scattering theory
J. M. Bang, A. I. Mazur, A. M. Shirokov +2
The relation between the R- and P-matrix approaches and the harmonic oscillator representation of the quantum scattering theory (J-matrix method) is discussed. We construct a discr…

IBM: parameter symmetry, hidden symmetries and transformations of boson operators
A. M. Shirokov, N. A. Smirnova, Yu. F. Smirnov +2
A symmetry of the parameter space of interacting boson models IBM-1 and IBM-2 is studied. The symmetry is associated with linear canonical transformations of boson operators, or, e…
