## What's this?

Web-Schrödinger is a program for the interactive solution of the stationary (time independent) and time dependent two dimensional (2D) Schrödinger equation.

## What's new?

• Ver 3.31 -- 13. April 2022
• Use secure protocol
• Ver 3.3 -- 29. September 2021
• Quadratic potential for rectangle now includes V0, Vx, Vy, Vxx, Vyy, Vxy terms.
• New examples for two coupled 1D particles: hard balls and coupled pendulums
• Ver 3.2 -- 15. January 2020
• Linear and quadratic potentials introduced
• New examples: projectile motion, harmonic oscillator, diatomic molecule
• Ver 3.1
• New Fourier transform algorithm (FFTW) makes the time dependent calculation run faster.
• Fixed a bug related to browser cache. The program didn't update correctly the images of the time development when the user changed the parameters.
