Diffraction in phase space: Jumps and kinks in matter waves revealed by their dynamics
We show that a discontinuity either in a wave function or its derivative, corresponding to a jump or a kink, causes ripples in Wigner phase space. In the free time evolution, these structures give rise to interference fringes in the probability density represented in spacetime.
