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…

Isolated States
A. M. Shirokov, Yu. F. Smirnov, S. A. Zaytsev
We show that a quantum system with nonlocal interaction can have bound states of unusual type (isolated states (IS)). IS is a bound state that do not generate a -matrix pole. IS…
