qcd_ml.base.operations.SU3_group_compose(A, B)

SU(3) group composition of two SU(3) fields.

qcd_ml.base.operations.link_gauge_transform(U, V)

Gauge-transforms a link-like field. A link-like is typically a gauge configuration.

qcd_ml.base.operations.mspin_const_group_compose(A, B)

Matrix-matrix multiplication for spin matrices.

qcd_ml.base.operations.v_gauge_transform(Umu, v)

Gauge transformation of vector-like fields.

qcd_ml.base.operations.v_ng_spin_const_transform(M, v)

Applies a spin matrix to a vector field without gauge freedom.

qcd_ml.base.operations.v_ng_spin_transform(M, v)

Applies a spin matrix field to a vector field without gauge freedom.

qcd_ml.base.operations.v_spin_const_transform(M, v)

Applies a spin matrix to a vector field.

qcd_ml.base.operations.v_spin_transform(M, v)

Applies a spin matrix field to a vector field.

qcd_ml.base.hop

Gauge-equivariant hops.

qcd_ml.base.hop.m_hop(U, mu, direction, m)

Gauge-equivariant hop for a matrix-like field.

qcd_ml.base.hop.v_hop(U, mu, direction, v)

Gauge-equivariant hop for a vector-like field.

qcd_ml.base.hop.v_ng_hop(mu, direction, v)

Hop for a vector-like field without gauge degrees of freedom.

qcd_ml.base.paths

Gauge-equivariant parallel transport paths.

The function v_evaluate_path is memory effective but slow.

The class PathBuffer can be used to speed up path evaluation but may be more memory intensve.

qcd_ml.base.paths.path_get_orig_point(path)

This funciton returns the point that will be transported to the point [0,0,0,0] by the path.
