Fred Cummings (also known as Frederick W. Cummings; November 21, 1931 - January 31, 2019)[1] was a theoretical physicist and professor at the University of California, Riverside.[2] He specialised in cavity quantum electrodynamics, many-body theory, non-linear dynamics, and biophysics.

Discoveries[]

Cummings obtained his PhD with Edwin Thompson Jaynes at Stanford University in 1962. After thirty years at University of California Riverside Physics department, Cummings became emeritus professor in 1993. He then lived in Marin County, California. Some of his important discoveries include the "Jaynes–Cummings model", one atom interacting with a quantized e-m field; as well as the extension of this to N atoms, the "Tavis-Cummings model". In the last twenty years his interest has turned to questions of biophysics of development and evolution.[3][4]

Academic career[]

Cummings was full professor at U.C. Riverside when he retired (emeritus) after thirty years at UCR.
