Tunneling through a parabolic barrier viewed from Wigner phase space
D. M. Heim, W. P. Schleich, P. M. Alsing +2
We analyze the tunneling of a particle through a repulsive potential resulting from an inverted harmonic oscillator in the quantum mechanical phase space described by the Wigner fu…
On the concepts of radial and angular kinetic energies
Jens Peder Dahl, Wolfgang P. Schleich
We consider a general central-field system in D dimensions and show that the division of the kinetic energy into radial and angular parts proceeds differently in the wavefunction p…
The s-wave implosion and explosion of free particles
I. Bialynicki-Birula, M. A. Cirone, J. P. Dahl +2
A free quantum particle in two dimensions with vanishing angular momentum (s-wave) in the form of a ring-shaped wave packet feels an attractive force towards the center of the ring…
