class kondoSC

Kondo-type spin-conserving single-impurity model.

This helper builds a local spin-only fermionic basis and constructs the exchange interaction between an impurity spin and a conduction-electron spin.

Public Functions

inline kondoSC(double JKondo, double spinS, double localDelta)

Construct the Kondo single-channel model.

Parameters:

• JKondo – Exchange coupling strength.

• spinS – Impurity spin magnitude.

• localDelta – Local superconducting pairing term or equivalent channel coupling.

inline std::vector<std::vector<int>> get_basis() const

Return the symmetry quantum numbers for each block.

Returns:

Quantum-number labels per block.

inline std::vector<std::vector<double>> get_eigenvaluesQ() const

Return the eigenvalues in each symmetry block.

Returns:

Block energies for the constructed Hamiltonian.

inline std::vector<double> get_chi_Q() const

Return the parity sign associated with each block.

Returns:

Parity factor used in fermionic symmetry bookkeeping.
