  • Intertwining Symmetry Algebras of Quantum Superintegrable Systems 
    Calzada, J.A.; Negro, J.; del Olmo, M.A. (Symmetry, Integrability and Geometry: Methods and Applications, 2009)
    We present an algebraic study of a kind of quantum systems belonging to a family of superintegrable Hamiltonian systems in terms of shape-invariant intertwinig operators, that span pairs of Lie algebras like (su(n),so(2n)) ...
  • Solutions of the Dirac Equation in a Magnetic Field and Intertwining Operators 
    Contreras-Astorga, A.; J. Fernández C., D.; Negro, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2012)
    The intertwining technique has been widely used to study the Schrödinger equation and to generate new Hamiltonians with known spectra. This technique can be adapted to find the bound states of certain Dirac Hamiltonians. ...
