Computational quantum physics
This section gathers the PortLAB tools for the numerical solution of the Schrödinger equation. The finite-difference suite deals with the bound states of one-dimensional and radial potentials — from harmonic and anharmonic oscillators to the double well, from molecular potentials (Morse, Pöschl–Teller, torsions and inversions) to nuclear-structure models (liquid-drop nuclei, deformations, giant dipole resonance, fission path).
Dedicated pages solve the hydrogen atom and the two-centre H2+ ion, while Schrödinger QMC estimates the ground-state energy of 18 molecules with the variational Monte Carlo method, computed in real time on the server. Where available, the Approfondimento tab of the individual pages tells their historical context and references.
