Detailed Description

Wilson fermion operator with SF BC.

This class implements the Wilson fermion operator with the SF BC.

  • The SF BC for the fermion field is:
    • The fermion field at t=0 is always set to zero (Dirichlet BC).
    • The field at t=1,...,Lt-1 is active.
  • Implemented by delegation of the Fopr_Wilson class like Fopr_Clover.
  • The modification is only in Fopr_Wilson_SF::D to set the boundary fermion field to zero before and after multiplication of the standard Wilson Dirac operator.
    • By this manipulation the SF BC is introduced in the fermion field.
  • A private function set_boundary_zero(Field&) is introduced for this bounadry manipulation.
  • A few private members are added for this function.
