Detailed Description

Clover fermion operator.

This class implements the clover (improved Wilson) fermion operator with SF BC.

  • The field strength is calculate when the function set_config() is called.
  • Dirac representation only!
  • [10 Apr 2012 Y.Taniguchi]

(Coding history will be recovered from trac.) YAML is implemented. [14 Nov 2012 Y.Namekawa] unique_ptr is introduced to avoid memory leaks [21 Mar 2015 Y.Namekawa]
