The calculation of the Green's function in getGMultiBand() for negative frequencies makes the assumption that the multi band Green's function in real space and imaginary time is real. This is...

For a 2x2 matrix, the smallInverse function does the inversion analytically and incorrectly switches the off-diagonal elements: std::swap(m_inv(1, 0), m_inv(0, 1)); This won't affect problems for which the Hamiltonian is...

Perturbation order increases with iteration for oblique cluster shapes

4

For Nc=12, "cluster": [[2, 2], [-4, 2]], and likely other oblique clusters, the perturbation order is found to increase with the DCA iteration. This is likely because the chemical potential...
