Detailed Description

Standard fermion action with SF BC for HMC.

This class defines an action with SF BC used in HMC.

• Generated by copying Action_F_Standard class.
• The argument Fopr and Force of the constructor should be implemented for the SF BC.
• The only modification is in Action_F_Standard_SF::langevin
  • For the calculation of the initial Hamiltonian the pre-pseudo fermion field xi is set to zero at the boundary.
  • A private function set_boundary_zero(Field&) is introduced for this bounadry manipulation.
  • A few private members are added for this function.
• The following properties are the same as those of the Action_F_Standard class.
  • Fermion and Force operators and given at the construction.
  • The solver is explicitly set to CG algorithm whose object is created in set_parameters().
• [05 Apr 2012 Y.Yusuke]

selector is implemented. [02 Feb 2013 Y.Namekawa] (Selectors are replaced with factories by Aoyama-san)
