Sudarshan was known for his works to the field of theoretical Physics including Optical coherence, Sudarshan-Glauber representation, V-A theory, Tachyons, Quantum Zeno effect, Open quantum system, Spin-statistics theorem, non-invariance groups, positive maps of density matrices, quantum computation among others.

His works include also relations between east and west, philosophy and religion.

In 2005, the Nobel Committee controversially did not award Sudarshan the Nobel Prize in Physics yet awarded his work about Glauber–Sudarshan P representation to Roy J. Glauber only.^[2]
