Methods

__init__(name[, reps])

bar(component)

The ψ̄ IndexedBase matching a gauge component.

charge(u1_group)

U(1) charge of this field (0 if not charged under it).

dag()

Hermitian conjugate of the component column: a row Matrix.

generators(group)

Generator matrices of group acting on this field's FULL component space (Kronecker product over all non-abelian reps).

Attributes

dim

spin

bar_components

Dirac adjoints ψ̄, one IndexedBase per gauge component

mat
