Contribution grade

Condensed matter physics · THEORY

Reference score210,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

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.
