Partha Ghose

Partha Ghose is one of India's best known popularizers of modern science. He has written influential papers and booksP. Ghose, Testing Quantum Mechanics on New Ground, Cambridge University Press, UK, April 1999." on physics as well as popular books on science.P. Ghose and D. Home, Riddles in Your Tea Cup, Rupa & Co., 1990, Adam Hilger, UK, Sept 1994. The book has been published in several Indian languages, Italian, Japanese and Turkish.P. Ghose, Solar Eclipse : The Celestial Diamond, Harper-Collins of India, 1996. He was an anchorperson in the popular Indian TV shows Quest and Eureka. He has directed plays and appeared in media programmes and films including the National Award-winning film 'The Quantum Indians', which is about great Indian scientists Satyendranath Bose, C. V. Raman and Meghnad Saha.

Ghose received the National Award for the Best Science and Technology coverage in the Mass Media of the National Council for Science and Technology Communication (NCSTC) for the period 1986–1990. He was also awarded the Indira Gandhi Prize for the popularization of science by the Indian National Science Academy.

He is best known in the physics world for his significant contributions to theoretical physics, particularly the foundations of quantum mechanics.

(i) His paper in collaboration with D. Home and G. S. AgarwalP. Ghose, D. Home and G. S. Agarwal, 'An Experiment to Throw More Light on Light', Physics Letters. A vol. 153, 403–406 (1991). (the GHA experiment) in unraveling the nature of wave–particle duality in single-photon experiments led to its experimental verification by Y. Mizobuchi and Y. OhtakeY. Mizobuchi & Y. Ohtake, 'An "experiment to throw more light on light"', Physics Letters A, vol. 168, pp. 1–5 (1992). in Japan and later by M. Genovese and collaboratorsG. Brida, M. Genovese, M. Gramegna and E. Predazi, ‘A conclusive experiment to throw more light on "light" ’, Physics Letters A, vol. 328, pp. 313–318 (2004). in Italy. This work has been widely referred to and has found place even in popular texts.,G. Venkataraman, Quantum Revolution: What is Reality, Vignettes in Physics, Sangam Books, 1994.John Gribbin, Schrődinger’s Kittens and the Search for Reality, Phoenix Paperback, 1996.

(ii) His work on Bohmian trajectories of photonsP. Ghose, A. S. Majumdar, S. Guha and J. Sau, ‘Bohmian trajectories for photons’, Physics. Letters A vol. 290, pp. 205-213 (2001). formed the basis for a comparison of these trajectories from those that were later observed experimentally with weak measurements.Sacha Kocsis, Sylvain Ravets, Boris Braverman, Kris-ter Shalm, Aephraim M. Steinberg: ‘Observing the trajectories of a single photon using weak measurement’, Science 3, June 2011, vol. 332 no. 6034, pp. 1170–1173, {{doi|10.1126/science.1202218}} (abstract)

(iii) He has also made a pioneering contribution by showing that 'entanglement' can occur in classical polarization optics resulting in violations of Bell-like inequalities hitherto believed to be exclusive to quantum systems.P. Ghose and M. K. Samal, ‘EPR Type Nonlocality in Classical Electrodynamics!’, arXiv: [quant-ph]/0111119, 22 November 2001. This has led to many investigations and experiments confirming such violationsP. Ghose and A. Mukherjee, ‘Entanglement in Classical Optics’, Reviews in Theoretical Science vol. 2, pp. 1-14 (2014). and consequently to a shifting of the boundary between quantum and classical physics.Xiao-Feng Qian, Bethany Little, John C. Howell, and J.H. Eberly, ‘Shifting the Quantum-Classical Boundary: Theory and Experiment for Statistically Classical Optical Fields’, arXiv: 1506.01305 [quant-ph] 25 June 2015.

Ghose's exposition of Rabindranath Tagore’s philosophy and music has found expression in several scholarly papers. He served as the Hon. Secretary of the Visva-Bharati Music Board for a few years.

He also served as a member of the Working Group on National Language Policy, Knowledge Commission, Govt of India.
