Detailed Description

Stout(exponential)-type projection to SU(N) gauge group.

Present implpementation applies to SU(3) case only, since the SU(3) properties are explicitly used. [08 Apr 2012 H.Matsufuru]

determination of fields for force calculation

See the implementation note "note_cloverHMC.pdf" (21 Mar 2012) by H.Matsufuru.
Evaluate $\Sigma_\mu'(x)\exp(iQ_\mu(x))+C_\mu^\dagger i\Lambda_\mu(x)$ and $i\Lambda_\mu(x)U_\mu(x)$ in eq.(93)
argument Sigmap $=\Sigma_\mu'(x)$ in eq.(93) in terms of (k)-th smearing.
argument Cst $=C_\mu(x)$ of eq.(43) in terms of (k-1)-th smearing.
argument Uorg $=U_\mu(x)$ in (k-1)-th smearing.
argument Xi is a resultant $\Sigma_\mu'(x)\exp(iQ_\mu(x))+C_\mu^\dagger i\Lambda_\mu(x)$ .
argument iTheta is a resultant $i\Lambda_\mu(x)U_\mu(x)$ .
