Bahram Mashhoon

Bahram Mashhoon (Persian: بهرام مشحون, born 9 September 1947) is an Iranian-American theoretical physicist who has contributed to the fields of special and general relativity. He is a Professor Emeritus of Physics in the Department of Physics and Astronomy at the University of Missouri in Columbia. He is known for formulating the Mashhoon effect.

Early life and education Bahram Mashhoon was born in Tehran, Iran, on 9 September 1947.

Career and research After completing his Ph.D., Mashhoon briefly served on the physics faculty of Arya-Mehr University (now Sharif University of Technology) in Tehran before returning to Princeton University as a research associate in 1973. gravitomagnetism, tidal dynamics, gravitational waves, and cosmology. Its existence is due to the inertia of intrinsic spin. In interferometry, the spin-rotation coupling in general appears in addition to the Sagnac effect that is due to the coupling of orbital angular momentum with rotation. The Mashhoon effect has been experimentally confirmed in neutron interferometry. The applications extend from the phenomenon of phase wrap-up in the Global Positioning System (GPS) to the spin-vorticity coupling in spintronics.

In 1993, Mashhoon introduced a nonlocal theory of accelerated systems in Minkowski spacetime. A comprehensive account of this theory of nonlocal gravity is contained in Mashhoon's book and astrophysical and cosmological implications of this theory have been investigated in connection with dark matter and dark energy.
