pmm_tools.models.parity_qubit_tunnel
Two real Kitaev chains joined by normal hopping, with no middle dot.
Fock ordering: (L1,...,LN,R1,...,RN); fixed total parity. The bridge is t_c (c_LN^dagger c_R1 + h.c.), without pairing. All parameters are in micro-eV. Both superconducting phases are zero, matching the current noise campaign. The many-body Hamiltonian is assembled by second_quantization through the existing open-chain constructor. No bridge elimination or low-energy projection is made here, including when t_c exceeds the clean chain gap.
