creation(edge, n, *, computational=False, jax=False)

annihilation(edge, n, *, computational=False, jax=False)

s(edge, no_i=False, *, computational=False, jax=True)

The symmetric holonomy operator s which increments or decrements the quantum number of the specified edge symmetrically by a value of 1.

c(edge, *, computational=False, jax=True)

The symmetric holonomy operator c which increments or decrements the quantum number of the specified edge symmetrically by a value of 1.

E(edge, power=1.0, *, computational=False, jax=True)

The flux operator which acts as a number operator but can additionally output eigenvalues raised to some power.

E_inv(edge, power=1.0, *, computational=False, jax=True)

The flux operator which acts as an ‘inverse’ number operator in the sense that it outputs 1/spin instead of spin as the eigenvalue. Additionally, it can output eigenvalues raised to some power.
