WebWave packets don't always spread out over time. For a free particle with a Gaussian wavepacket, the width actually decreases for an arbitrarily long time before eventually increasing again. The Heisenberg uncertainty product Δ x × Δ p can also decrease (although of course it can never go below ℏ / 2 ). Share. Cite. WebWe present a Fourier analysis of the first order wave equation in a periodic domain subject to a class of high-order continuous and discontinuous discretizations with either centered or upwind flux. This allows us to analytically derive the dispersion relation, group velocity and identify the emergence of gaps in the dispersion relation at specific wavenumbers. Wave …
