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[2])this physicist’s namesake field, since the anticommutator of this physicist’s namesake (*) gamma matrices equals two (10[1]-5[1])times the metric tensor. This physicist created bra-ket notation (10[3])to simplify (10[1])quantum mechanical expressions. (10[1]-5[1])This physicist co-names the quantum statistics for identical particles with half integer spins with Enrico Fermi. (10[1]-5[1])For 10 points, name this English physicist who used his namesake field equation to predict the existence of antimatter. ■END■ (0[1])
