Ennackal Chandy George Sudarshan
Ennackal Chandy George Sudarshan is an Indian
theoretical physicist and a professor at the
University of Texas. Sudarshanan has been credited
with numerous contributions to the field of
theoretical Physics including Optical coherence,
Sudarshan Glauber representation,V-A theory,
Tachyons, Quantuam Zeno effect , Open quantum
system ,Spin statistics theorem , non invariance
groups, positive maps of density matrices , quantum
computation among others . His contributions
include also relations between east and west,
philosophy and religion.
George Sudarshan was born in a Syrian
Christian family in Pallam , Kottayam district,
Kerala,India.Despite being raised in a Christian
family, he later left the religion and called himself a
“Vedantin”.He mentions disagreements with the
Church’s view on God and lack of spiritual
experience as reason why he left the Church.

He studied at CMS College Kottayam and
graduated with honors from the Madras Christian
College in 1951.He obtained his master’s degree at
the university of Madras in 1952 .He moved to Tata
Institute of Fundamental Research(TIFR
)and worked there for a brief period with Homi
Bhaba as well as others. Subsequently, he moved to
University of Rochester in New York.
Sudarshan has made significant contributions
to several areas of physics. He was the originator of
the V-A theory of the weak force, which eventually
paved the way for the electroweak theory.
Feynman acknowledged Sudarshan’s contribution in
1963 stating that the V-A theory was discovered by
Sudharshanan and Marshak and publicized by Gell-
Mann and himself. He also developed a quantum
representation of coherent light later known as
Sudharshan-Glauber representation
Sudarshan’s most significant work might be
his contribution to the field of quantum optics. His

theorem proves the equivalence of classical wave
optics to quantum optics. Sudarshan was also the
first to propose the existence of Tachyons, particles
that travel faster than light .He developed
formalism called dynamical maps that is one of the
most fundamental formalism to study the theory of
open quantum system .He, in collaboration with
Baidyanth Misra, also proposed the quantum Zeno
effect. Sudarshan and collaborators initiated the
“Quantum theory of charged particle beam
optics”,by working out the focusing action of
,magnetic quadrupole using the Dirac Equation.
