spinless fermions with nearest-neighbor interactions in 1d
----------------------------------------------------------

This example makes use of the `user_basis` class of `basis_general` to show how to construct spinless fermion systems with symmetries.

Please consult this post: :ref:`user_basis-label`, for more detailed explanations for using the `user_basis` class.
