Detailed Description

template<class repr>
class represented_gauge_field< repr >

A gauge field, similar to the standard gauge_field class above, but with the gauge field projected into a higher representation.

Member Typedef Documentation

gauge_type_flt

using gauge_field_base< repr >::gauge_type_flt = repr

inherited

If the base type is double, this will be the corresponding floating point type.

Definition at line 47 of file gauge_field.h.

Member Function Documentation

add_momentum()

template<class repr >

void represented_gauge_field< repr >::add_momentum ( Field< SquareMatrix< N, Complex< basetype > > >(&)  force[4] )

inline

Project a force term to the algebra and add to the momentum

Definition at line 347 of file gauge_field.h.

backup()

template<class repr >

void represented_gauge_field< repr >::backup ( )

inlinevirtual

Make a backup of the fundamental gauge field Again, this may get called twice.

Reimplemented from gauge_field_base< repr >.

Definition at line 366 of file gauge_field.h.

draw_momentum()

template<class repr >

void represented_gauge_field< repr >::draw_momentum ( )

inlinevirtual

This gets called if there is a represented gauge action term. If there is also a fundamental term, it gets called twice...

Reimplemented from gauge_field_base< repr >.

Definition at line 359 of file gauge_field.h.

random()

template<class repr >

void represented_gauge_field< repr >::random ( )

inlinevirtual

Draw a random gauge field. This will set the underlying fundamental field

Reimplemented from gauge_field_base< repr >.

Definition at line 340 of file gauge_field.h.

set_unity()

template<class repr >

void represented_gauge_field< repr >::set_unity ( )

inlinevirtual

Set the gauge field to unity. This will set the underlying fundamental field

Reimplemented from gauge_field_base< repr >.

Definition at line 333 of file gauge_field.h.

Member Data Documentation

momentum

Field<repr > gauge_field_base< repr >::momentum[4]

inherited

Also create a momentum field. This is only allocated if necessary
