fastdla.generators.spin_chain

Symmetry operations common to 1D spin-chain models.

Functions

magnetization_eigenspace(magnetization[, ...])
magnetization_projection(magnetization, ...)	Return a function that projects out the eigensubspace of magnetization.
parity_eigenspace(sign[, basis, num_spins, ...])	Extract the parity eigenspace.
parity_reflection(num_spins[, ...])	Return a function that applies a parity reflection to states.
spin_flip([npmod])	Return a function that applies a global spin flip \(\Pi_{\mathbb{Z}_2}\).
spin_flip_eigenspace(eigval[, basis, ...])	Extract the +1/-1 eigenspace of the global spin flip \(\Pi_{\mathbb{Z}_2}\).
translation(num_spins[, shift, npmod])	Return a function that applies the translation \(T_s\) to state vectors.
translation_eigenspace(jphase[, basis, ...])	Extract an eigenspace of the translation.
