virtual void calculateEigenvalues(Tensor &eigenvectors, Tensor &eigenvalues) override

Calculate the hamiltonian eigenvalues and eigenvectors, i.e. the effective Mass^2 states and effective mixing matrix.

Parameters:

  • eigenvectors โ€“ [out] The returned eigenvectors

  • eigenvalues โ€“ [out] The corresponding eigenvalues

Tensor getElectronOuterProduct()

construct the outer product of the electron row of the mixing matrix, used in building the hamiltonian, and return a copy of it potentially useful for debugging

Tensor getHamiltonian()

construct the hamiltonian and return a copy of it potentially useful for debugging

void buildElectronOuterProduct()๏ƒ

construct the outer product of the electron neutrino row of the mixing matrix used to construct the hamiltonian

void buildHamiltonian()๏ƒ

Construct the hamiltonian.
