Detailed Description

SU(N) gauge field class in which a few functions are added for the SF.

This class defines SU(N) gauge field, which is used such as gauge configuration.

  • A derived class from Field_G in order to add a few functions to manipulate the boundary link variables.
  • An inheritance was adopted since we need to manipulate the Field contents and upcast into Filed_G object.
  • [23 Mar 2012 Y.Taniguchi]

Member Function Documentation

void Field_G_SF::mult_ct_boundary ( const int  t,
const double  ct 
)

Multiply the boundary improvement factor ct or ctr to an SU(N) matrix object which belongs to a site at t.

Multiply the boundary improvement factor ct or ctr to an SU(N) matrix object attached to the boundary t=0 or t=Nt.

  • Supposed to be used for a matrix given by upper(g,mu,nu) or lower(g,mu,nu) when it is attached to the t=0 boundary.
  • The SU(N) matrix object may belong to a site at t=0 or t=1 or t=Nt.
  • This function performs no check if the object is a proper one at the boundary.
  • Lorentz index is set to mn=0.
  • Introduced by Yusuke Taniguchi for SF bc.
