How it works

The way this simulator works is by discretizing and Hamiltonian of an arbitrary potential, specified as a function of the particle observables. This is achieved with the Hamiltonianconstructor. Then, the Hamiltonian.solve method efficiently diagonalizes the Hamiltonian and outputs the energies and the eigenstates of the system. Finally, the eigenstates can be plotted with the visualization class.

The visualization.superpositions method features the possibility of interactively visualizing a superposition of the computed eigenstates and studying the time dependence of the resulting wavefunction.

For efficiently solving the time dependent Schrödinger equation, TimeSimulation class must be used. It takes as an argument the Hamiltonian you have previously defined, and the method you desire to use.

For a quick start, take a look to the examples found in the examples subdirectory.
