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…

Quantum Carpets made simple
I. Marzoli, F. Saif, I. Bialynicki-Birula +3
We show that the concept of degeneracy is the key idea for understanding the quantum carpet woven by a particle in the box.

The Particle in the box: Intermode traces in the propagator
I. Marzoli, I. Bialynicki-Birula, O. M. Friesch +2
Characteristic structures such as canals and ridges --intermode traces-- emerge in the spacetime representation of the probability distribution of a particle in a one-dimensional b…
