||Rudolf Haag (b. 17 August 1922) was a German physicist. He was best known for his contributions to the algebraic formulation of axiomatic quantum field theory (QFT), namely the Haag–Kastler axioms, and a central no-go theorem in QFT, Haag's theorem, which demonstrates the nonexistence of a unitary time-evolution operator in the interaction picture. Pic.
