Biography of ECG Sudarshan - Raichal C

 Ennackal Chandy George Sudarshan (also known as E. C. G. Sudarshan) was born in the Kerala town of Kottayam in the year 1931. Before going to the University of Madras and then the Tata Institute of Fundamental Research, he attended CMS College in his hometown. Later, he studied and taught at the University of Rochester, and then for nearly 40 years at the University of Texas at Austin. Sudarshan was India's best-known theoretical physicist, and at the time of his death, he was a professor emeritus at the University of Texas at Austin in the United States.

Sudarshan made major contributions to physics in a number of fields. He developed the V-A weak force hypothesis, which cleared the path for the electroweak theory. Sudarshan's contribution was acknowledged by Feynman in 1963, who stated that the V-A theory was found by Sudarshan and Marshak and disseminated by Gell-Mann and himself. He also created the Glauber–Sudarshan representation, a quantum representation of coherent light. 

Sudarshan's most important contribution may have been to the subject of quantum optics. His theorem establishes the equivalence of classical and quantum wave optics. The Sudarshan representation is used in the theorem. This description also predicts purely quantum optical events that cannot be described traditionally. Sudarshan was also the first to suggest that tachyons, particles that travel faster than light, exist. To examine the theory of open quantum systems, he established a foundational formalism called dynamical maps. He also proposed the quantum Zeno effect in cooperation with Baidyanath Misra.

He died of natural causes in 13th of May 2018.
