Bound and scattering states of a non-central extension of the three-dimensional Kepler–Coulomb Hamiltonian are worked out analytically within the framework of the potential groups of the problem, SO(7) for bound states and SO(6, 1) for scattering states. In the latter case, the S-matrix is calculated by the method of intertwining operators. 

Lie-algebraic interpretation of the maximal superintegrability and exact solvability of the Coulomb–Rosochatius potential in n dimensions

The potential group method is applied to the n-dimensional Coulomb–Rosochatius potential, whose bound states and scattering states are worked out in detail. As far as scattering is concerned, the

Revisiting the symmetries of the quantum smorodinsky-winternitz system in D dimensions

The D-dimensional Smorodinsky{Winternitz system, proposed some years ago by Evans, is re-examined from an algebraic viewpoint. It is shown to possess a potential algebra, as well as a dynamical

Behavior of an electron in the vicinity of a tridimensional charged polar nanoparticle through a classical and quantum constant of motion

We present a classical and a quantum constant of motion used to study the behavior of an electron moving in the vicinity of a tridimensional charged nanostructure with electric dipole. It is the

Bidimensional bound states for charged polar nanoparticles

We study the behavior of an electron in the vicinity of a positively charged nanoparticle that has a permanent electric dipole and is of finite size (not point-like) in two dimensions. We place

Quantum scattering from the Coulomb potential plus an angle-dependent potential: a group-theoretical study

The nonrelativistic quantum scattering problem for a non-central potential which belongs to a class of potentials exhibiting an ‘accidental’ degeneracy is studied. We show that the scattering system

Algebraic Calculation of Nonrelativistic Coulomb Phase Shifts

It is observed that the in and out states of a particle of energy k2/2m, entering or leaving a Coulomb field along the +z direction, are eigenstates of L3 with eigenvalue 0, and of A3, the third

Non-spherically symmetric transparent potentials for the three-dimensional Schrödinger equation

A class of transparent potentials (i.e., potentials with trivial scattering operator S = 1) for the three-dimensional Schrödinger equations is studied. We find the underlying group explaining the

Quantum completely integrable systems connected with semi-simple Lie algebras

The quantum version of the dynamical systems whose integrability is related to the root systems of semi-simple Lie algebras are considered. It is proved that the operators Ĵk introduced by Calogero

Superintegrability with second- and third-order integrals of motion

Superintegrable systems in two-dimensional Euclidean space E2 with scalar potentials and integrals of motion that are second- or third-order polynomials in the momenta are discussed. We review old

Algebraic approach to non-central potentials

An algebraic approach to class of separable non-central Hamiltonians is presented. We show that the bound states of quantum systems under consideration are described by unitary representations of the

A new superintegrable Hamiltonian

We identify a new superintegrable Hamiltonian in three degrees of freedom, obtained as a reduction of pure Keplerian motion in six dimensions. The new Hamiltonian is a generalization of the Keplerian

New Soluble Energy Band Problem

The Schrodinger equation for V(x) = - V0 csc2(πx/a) is solved. E(k) and the effective mass are examined along with the wave functions for various values of the parameter (V0a2). It is found that the
