Refresh pseudofermions.

This routine calculates the pseudofermion field (chi) for the case of rational evolution

      chi =  n(Q)*[d(Q)]^(-1) * eta

Where: Q = M^dag*M d(Q) = (Q+q_1)*(Q+q_2)*...*(Q+q_m) n(Q) = (Q+p_1)*(Q+p_2)*... *(Q+p_m) m = HBRatDeg

The rational function n(x)/d(x) is the optimal rational approximation to the inverse square root of N(x)/D(x) which in turn is the optimal rational approximation to x^(-alpha). Here, alpha = 1/2

To solve {n(Q)*[d(Q)]^(-1) * eta} the partial fraction expansion is used in combination with a multishift solver.

Implements Chroma::ExactWilsonTypeFermMonomial< P, Q, Phi >.

Compute the action on the appropriate subset.

This measures the pseudofermion contribution to the Hamiltonian for the case of rational evolution (with polynomials n(x) and d(x), of degree SRatDeg

S_f = chi_dag * (n(A)*d(A)^(-1))^2* chi

where A is M^dag*M

The rational function n(x)/d(x) is the optimal rational approximation to the square root of N(x)/D(x) which in turn is the optimal rational approximation to x^(-alpha). Here, alpha = 1/2
