Detailed Description

Recursive calculation of HYP smeared fermion force with SF BC.

26 May 2012 Y.Taniguchi 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" (2 Apr 2012) by H.Matsufuru.
  • m_U[mu] $=U_{\mu}(x)$ is (k-1)-th smeared 0-th level link.
  • Xi is used as $\Xi_\mu^{(1)}(x)=\Sigma_{\mu;\nu\rho}^{(2)}(x)\exp(iQ_{\mu;\nu\rho}^{(1)}(x))+C_{\mu;\nu\rho}^{(1)\dagger}i\Lambda_{\mu;\nu\rho}^{(1)}(x)$ and is to be added to Sigma for the (k-1)-th smeared force.
  • m_iTheta1[idx1b(mu,nu,rho)] is $i\Lambda_{\mu;\nu\rho}^{(1)}(x)U_\mu(x)$.
  • The force field Sigma is set to zero for the boundary spatial link.
