The four potential couples to a quantum field named for this scientist in the interaction Hamiltonian of quantum electrodynamics. In the non-relativistic limit, this scientist’s namesake equation reduces to the Pauli equation. Anti-commutation rules must be applied to quantize (15[1])this physicist’s namesake field, since the anticommutator of this physicist’s namesake (*) gamma matrices equals two (-5[1])times the metric tensor. This physicist created bra-ket notation (10[1])to simplify (10[1])quantum mechanical expressions. This physicist co-names the quantum statistics for identical particles with half integer spins with Enrico Fermi. For 10 points, name this English physicist who used his namesake field equation to predict the existence of antimatter. ■END■
