S impurity solver instance n_w nb of matsubara frequencies beta inverse temperature mu chemical potential V hybridization strength

g coupling to the spin subohmic bath wc cutoff frequency for subohmic bath s exponent of the subohmic bath

l charge w0 holstein frequency for charge-charge interactions

sign sign in front of expression for spin-spin interactions

Note: Kz defined as: Kz’’(tau) = Dz(tau) ; Kz(0^{+}) = Kz(beta^{-}) = 0 J_perp( au) = 4 Dz( au) in the rotation invariant case
