Gerald Mahan

Gerald Dennis Mahan (November 24, 1937 – November 21, 2021) was an American condensed matter physicist, with specific research interests in transport and optical properties of materials, and solid-state devices. He is recognized for his work in quantum thermoelectricity and the invention of the zinc oxide varistor. He is also developed the time-dependent local-density approximation (TDLDA) and its author of various books in quantum many-body physics.

Mahan worked at General Electric Research Laboratory (1963–1967) and was a professor of physics at the University of Oregon (1967–1973), Indiana University (1973–1984), University of Tennessee (1984–2001), and Pennsylvania State University (2001–2021). He also worked at Oak Ridge National Laboratory (1984–2001). Provided by Wikipedia
