Detailed Description

Recursive calculation for APE smeared fermion force.

08 Apr 2012 H.Matsufuru YAML is implemented. [14 Nov 2012 Y.Namekawa] unique_ptr is introduced to avoid memory leaks [21 Mar 2015 Y.Namekawa]

  • Each block evaluates:
  • The 1st block: $-U_\nu(x+\mu)U_\mu^\dagger(x+\nu)U_\nu^\dagger(x)\Lambda_\nu(x)$
  • The 2nd block: $-U_\nu^\dagger(x+\mu-\nu)U_\mu^\dagger(x-\nu)\Lambda_\mu(x-\nu)U_\nu(x-\nu)$
  • The 3rd block: $U_\nu^\dagger(x+\mu-\nu)U_\mu^\dagger(x-\nu)\Lambda_\nu(x-\nu)U_\nu(x-\nu)$
  • The 4th block: $\Lambda_\nu(x+\mu)U_\nu(x+\mu)U_\mu^\dagger(x+\nu)U_\nu^\dagger(x)$
  • The 5th block: $-U_\nu^\dagger(x+\mu-\nu)\Lambda_\mu(x+\mu-\nu)U_\mu^\dagger(x-\nu)U_\nu(x-\nu)$
  • The 6th block: $-U_\nu(x+\mu)U_\mu^\dagger(x+\nu)\Lambda_\mu(x+\nu)U_\nu^\dagger(x)$

  • See the implementation note "note_cloverHMC.pdf" (21 Mar 2012) by H.Matsufuru.
  • Sigmap $=\Sigma_\mu'(x)$ in eq.(93) in terms of (k)-th smearing.
  • U $=U_\mu(x)$ in (k-1)-th smearing.
  • Xi is used as $\Sigma_\mu'(x)\exp(iQ_\mu(x))+C_\mu^\dagger i\Lambda_\mu(x)$.
  • m_iTheta[mu] is $i\Lambda_\mu(x)U_\mu(x)$.
  • The pre-force field Sigma $=\Sigma_\mu(x)$ is set to zero for the boundary spatial link.
