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]
Field_G_SF and Field_F_SF classes are integrated to Field_SF namespace and converted to functions [26 Jan 2023 H.Matsufuru]

Function Documentation

void Field_SF::mult_ct_boundary	(	Field_G &	u,
		const int	t,
		const double	ct
	)

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.

void Field_SF::set_boundary_spatial_link_zero ( Field_G & u )

Set the boundary spatial link to zero.

Supposed to be used for a force for the boundary spatial link in order to keep it zero.
Lorentz index mn runs for spatial value.
Introduced by Yusuke Taniguchi for SF bc.

Definition at line 151 of file field_SF.cpp.

Set the boundary spatial link $U_k(t=0)$ to its proper Dirichlet bounday $W_k$ .

Supposed to be used for u_mu given by u_mu.setpart_ex(0, *g,mu) when mu is a spatial.
Lorentz index is set to mn=0.
Field is given as an argument.

void Field_SF::set_boundary_wkpr	(	Field_G &	u,
		const Mat_SU_N &	wkpr
	)

Set the boundary spatial link $U_k(t=N_t-1)$ to its proper Dirichlet bounday $W_k'$ .

Supposed to be used for v given by shift.backward(v,u_nu,mu) when mu is a temporal.
Lorentz index is set to mn=0.
Field is given as an argument.
