SU2 Operators

ed_lgt.operators.SU2_operators.SU2_Hamiltonian_couplings(lattice_dim, pure_theory, g, m=None)[source]

This function provides the couplings of the SU2 Yang-Mills Hamiltonian starting from the gauge coupling g and the bare mass parameter m

Parameters:

  • pure_theory (bool) – True if the theory does not include matter

  • g (scalar) – gauge coupling

  • m (scalar, optional) – bare mass parameter

Returns:

dictionary of Hamiltonian coefficients

Return type:

dict

ed_lgt.operators.SU2_operators.SU2_rishon_operators(spin)[source]

This function computes the SU2 the Rishon modes adopted for the SU2 Lattice Gauge Theory for the chosen spin-s irrep-resentation

Parameters:

spin (half/integer) – maximal spin-representation of the rishon operators

Returns:

dictionary with the rishon operators and the parity

Return type:
