e/Luttinger's theorem

Information
has gloss	eng: In condensed matter physics, Luttingers theorem is a result derived by J. M. Luttinger and J. C. Ward in 1960 that has broad implications in the field of electron transport. It arises frequently in theoretical models of correlated electrons, such as the high-temperature superconductors, and in photoemission, where a metals Fermi surface can be directly observed.
lexicalization	eng: Luttinger's theorem
