Renowned physicist George Sudarshan cremated in US

Press Trust of India  |  Houston 

Eminent Indian-American theoretical EC George has been cremated in the US state of Texas, with his family and friends attending the last rites.

Sudarshan, 86, who is survived by his wife Bhamathi and two children, died of natural causes on May 13 in Austin,

His two sons and Ashok performed the last rites at the near His wife Bhamathi sang Sudarshan's favourite song on Goddess Saraswathi.

The University of at Austin, where he worked since 1969, mourned his passing away. Several students and faculty from the department attended the service and spoke highly of the and his works.

General of at was represented by

Sam Kannappan, a close friend of for the past 50 years, has proposed that a scholarship or a lecture series may be established in the name of the eminent

Sudarshan, an outstanding theoretical physicist, was born in Kottayam, in 1931. The professional career of Sudarshan spans five decades.

He was a distinguished member of the Faculty at the University of from 1969.

He was nominated for Nobel Prize in nine times but was never awarded.

Sudarshan was awarded the Dirac Medal in 2010, which is known to be given out to scientists who have made substantial contributions in theoretical physics, and mathematics.

His numerous contributions to theoretical physics include the V-A Weak Interaction unification, symmetry groups in quantum field theory, the Sudarshan p representation, superluminal motion, spin and statics, quantum optical coherence, quantum Zeno effect and the infamous tachyon, the particle that moves faster than the speed of light.

He received his Ph.D. from the in 1958 and then moved to to work with as a postdoctoral fellow.

After serving on the faculties of the and Syracuse University, he settled at the at in 1969.

In 2007, the recognised and awarded the with the second highest civilian award

A of physics at the at from 1969 to 2016, he made many important contributions to theoretical physics on the (1977) and the Dirac Medal (2010).

Working with his Ph.D. Robert Marshak, Sudarshan created the V-A theory of the weak force, a discovery that was crucial to the unification of the weak and electromagnetic interactions by Steven Weinberg, and Sheldon Glashow, which in turn led to the 1979 Nobel Prize in Physics.

Along with Roy Glauber, Sudarshan developed a quantum mechanical description of light that would become the foundation of a new field: quantum optics. Glauber went on to share the 2005 Nobel Prize in Physics for that work.

Sudarshan and his graduate student V K Deshpande first proposed the existence of particles called tachyons that would violate Einstein's theory of relativity by travelling faster than the speed of light.

They would also have the bizarre consequence of allowing signals to be received by an observer before it was actually sent, violating the principle of causality.

So far, no experimental evidence has been found to support their existence.

Even during his tenure at the at Austin, he continued to contribute to research and in India, serving as a senior at the Center for Theoretical Studies at the (1971- 1991) and of the in Chennai (1984-1991).
