Ennackal Chandy George Sudarshan (also known as E. C. G. Sudarshan; 16 September 1931 – 13 May 2018)^[2][3] was an Indian American^[4] theoretical physicist and a professor at the University of Texas. Prof.Sudarshan has been credited with numerous contributions to the field of theoretical physics, including Glauber–Sudarshan P representation, V-A theory, tachyons, quantum Zeno effect, open quantum system and quantum master equations, spin–statistics theorem, non-invariance groups, positive maps of density matrices, and quantum computation.
