This person? https://en.wikipedia.org/wiki/Philip_W._Anderson https://en.wikipedia.org/wiki/Philip_W._Anderson "From 1949 to 1984, Anderson was employed by Bell Laboratories in New Jersey, where he worked on a wide variety of problems in condensed matter physics. During this period he developed: - what is now called Anderson localization (the idea that extended states can be localized by the presence of disorder in a system) - Anderson's theorem (concerning impurity scattering in superconductors); - invented the Anderson Hamiltonian, which describes the site-wise interaction of electrons in a transition metal; proposed symmetry breaking within particle physics (this played a role in the development of the Standard Model and the development of the theory behind the Higgs mechanism, which in turn generates mass in some elementary particles); - created the pseudospin approach to the BCS theory of superconductivity; - made seminal studies of non-s-wave pairing (both symmetry-breaking and microscopic mechanism) in the superfluidity of He3, - and helped found the area of spin-glasses."
