Fourier Grid Hamiltonian (FGH) method for high-precision 1D quantum calculations

Installation

A python virtual environment is recommended. Example using Linux:

$ git clone https://github.com/pedersor/fourier_grid_hamiltonian.git
$ cd fourier_grid_hamiltonian
$ python3 -m pip install pip --upgrade
$ python3 -m pip install .

Note that this code uses Cython, so the above installation through setup.py is recommended.

Example

Please check examples/example.py for a simple example using the Poschl-Teller potential.
