What changed
Derived gauge-consistent superconducting response with collective quasiparticle-pair excitations.
Scientific scope
The record is Nambu's sole-author 1960 Physical Review paper. It does not absorb BCS theory, the Nambu-Jona-Lasinio model, every development in spontaneous symmetry breaking or later experimental work.
