)

[inline, virtual]

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.

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
