scqubits.FullZeroPi.g_phi_coupling_matrix¶ FullZeroPi.g_phi_coupling_matrix(zeropi_states)[source]¶ Returns a matrix of coupling strengths \(g^\phi_{ll'}\) [cmp. Dempster et al., Eq. (18)], using the states from the list zeropi_states. Most commonly, zeropi_states will contain eigenvectors of the DisorderedZeroPi type. Return type: ndarray Parameters: zeropi_states (ndarray)
