Wigner Distribution Functions and the Representation of Canonical Transformations in Time-Dependent Quantum Mechanics
Dieter Schuch, Marcos Moshinsky
For classical canonical transformations, one can, using the Wigner transformation, pass from their representation in Hilbert space to a kernel in phase space. In this paper it will…
Alternative Method for Determining the Feynman Propagator of a Non-Relativistic Quantum Mechanical Problem
Marcos Moshinsky, Emerson Sadurni, Adolfo del Campo
A direct procedure for determining the propagator associated with a quantum mechanical problem was given by the Path Integration Procedure of Feynman. The Green function, which is…
Atom laser dynamics in a tight-waveguide
A. del Campo, I. Lizuain, M. Pons +2
We study the transient dynamics that arise during the formation of an atom laser beam in a tight waveguide. During the time evolution the density profile develops a series of wiggl…
Time modulation of atom sources
A. del Campo, J. G. Muga, M. Moshinsky
Sudden turn-on of a matter-wave source leads to characteristic oscillations of the probability density which are the hallmark feature of diffraction in time. The apodization of mat…
Transient Phenomena in Quantum Bound States Subjected to a Sudden Perturbation
Marcos Moshinsky, Emerson Sadurní
Transient phenomena in quantum mechanics have been of interest to one of the authors (MM) since long ago and, in this paper, we focus on the problem of a potential V_- which for ne…
Tunneling out of a time-dependent well
Tobias Kramer, Marcos Moshinsky
Solutions to explicit time-dependent problems in quantum mechanics are rare. In fact, all known solutions are coupled to specific properties of the Hamiltonian and may be divided i…
