Dirichlet
This script simulates the time evolution of a quantum mechanical wavepacket on the unit square with Dirichlet boundary conditions. Spatial discretization is with a Chebyshev-tau spectral method and time discretization is with a second order Crank-Nicholson method.

UPPSALATOR is an electroosmotical oscilLATOR developed in UPPSALA by T. Teorell. Up to now oscillations were observed only at constant currrent. Oscillations at constantvoltage were considered earlier as impossible. This program demonstrates the UPPSALATOR at any constant voltage.It solves...
