Remembering ECG Sudarshan - Jima Joseph

 Ennackal Chandy George Sudarshan  as C. G. Sudarshan was born in the Kerala town of Kottayam in the year 1931. He did his bachelors from CMS college and masters from Tata Institute of Fundamental Research (TIFR). Sudarshan had made numerous contributions to the field of theoretical physics, which includes Glauber–Sudarshan P representation, V-A theory, tachyons, quantum Zeno effect, open quantum system, spin–statistics theory. He was the originator  of the V-A theory of the weak force which eventually paved the way for the electroweak theory. Sudarshan's contribution in 1963 stating that the V-A theory was discovered by Sudarshan and Marshak .He also developed a quantum representation of coherent light later known as Glauber–Sudarshan representation. 

Sudarshan's most important contribution was in the  field of quantum optics. His theorem proves the equivalence of classical wave optics to quantum optics. This representation also predicts optical effects that are purely quantum, and cannot be explained classically. Sudarshan was also the first to propose the particles that travel faster than light. He developed a fundamental formalism called dynamical maps to study the theory of open quantum system. He also proposed the quantum Zeno effect. He was also professor of Physics at The University of Texas at Austin and a senior professor at the Indian Institute of Science. He worked as the director of the Institute of Mathematical Sciences Chennai. Later he died in the age of 86 in United States.
