  • Supersymmetry Transformations for Delta Potentials 
    David J. Fernández C.; Gadella, M.; Nieto, L.M. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    We make a detailed study of the first and second-order SUSY partners of a one-dimensional free Hamiltonian with a singular perturbation proportional to a Dirac delta function. It is shown that the second-order transformations ...
  • Time Asymmetric Quantum Mechanics 
    Bohm, A.R.; Gadella, M.; Kielanowski, P. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    The meaning of time asymmetry in quantum physics is discussed. On the basis of a mathematical theorem, the Stone-von Neumann theorem, the solutions of the dynamical equations, the Schrödinger equation (1) for states or the ...
