Born in Akhtiyarpur, in the Indian state of Bihar, KP Sinha passed his matriculation examination in 1944 and completed the intermediate studies in 1946 before joining Allahabad University to earn a BSc in 1948.[2] Subsequently, on completion of his MSc in 1950 from the same institution, he enrolled at Savitribai Phule Pune University for his doctoral studies under the guidance of GI Finch and secured a PhD in solid state physics in 1956.[3] Moving to the UK, Sinha did his post-doctoral work at the laboratory of Maurice Henry Lecorney Pryce during 1957-59, and his studies there in theoretical physics earned him a second PhD from the University of Bristol in 1965.[2]
In 1959, Sinha had returned to India to join the National Chemical Laboratory as a group leader at the Solid State and Molecular Physics Unit. He carried out research there until 1968, when he had an opportunity to join Bell Labs in New Jersey. Sinha's stay at the Murray Hill facility lasted two years. On his return to India in 1970, he joined the Indian Institute of Science as a senior professor at the department of physics, commencing a service which would last over three and a half decades. During this period, Sinha chaired a number of divisions such as the Division of Applied Mathematics (1971-73 and 1975-77) and the Centre for Theoretical Studies (1972-73 and 1981-87) for two terms each, and the Division of Physics and Mathematics from 1972 to 1976. On his superannuation from regular service in 1990, Sinha continued his association with IISc as a senior scientist of the Indian National Science Academy (INSA) during 1990-93, as a distinguished scientist of the Council of Scientific and Industrial Research from 1996 to 1998, and as an INSA honorary scientist since 2006.[2]
Sinha, who held the position of emeritus professor of the Indian Institute of Science since his superannuation,[4] lived in Dollars Colony, in Bengaluru.[5] He died there on 23 January 2023, at the age of 93.[6]
Legacy
The potential energy surfaces of an E ⊗ e Jahn–Teller effect
Sinha's theoretical work covered various aspects of solid state physics and he has made significant contributions in the field of crystal magnetism.[7] His early work during his doctoral and post-doctoral days was based on condensed matter theory, semiconductors, quantum well, Cold Fusion, phonons, and photon-induced effects in solids.[2] Later, Sinha worked on the origin of giant magnetic moments as well as exciton and electronphase transitions in solids, and developed an electronic pairing mechanism related to bosons and biexcitons for predicting the phenomenon of photon. He elucidated superconductivity at high temperatures by way of a non-equilibrium mechanism[8] and also developed a statistical theory on the origin of ferroelectricity and structural phase transitions induced by cooperative Jahn-Teller effect; his work on the magnetism is described in one of his books.[9] The luminescence efficiency of solids, Ricci scalar curvature, super strong gravity, singularity free cosmology, and low energy nuclear reactions are some other areas he has worked on.[3]
Sinha's studies have been documented by way of a number of articles,[10][note 2] and online article repositories such as Google Scholar and ResearchGate have listed many of them.[11][12] He has published 6 books which included Foundry Technology,[13]Interactions in magnetically ordered solids,[14]Aspects of Gravitational Interactions,[15]High Temperature Superconductivity: Current Results and Novel Mechanisms[16] and Magnetic superconductors: recent developments.[17] and has contributed chapters to books published by others[18][19][20] His work has also drawn citations from a number of authors.[21][22][23][24] and he has supervised the doctoral and post doctoral studies of 45 scholars.[2]
Sinha, a founder fellow of the Indian Cryogenic Council, was elected as a fellow by the Indian Academy of Sciences in 1971[25] and he was selected as a national professor by the University Grants Commission of India in 1972, a post he held for one year.[3] The Council of Scientific and Industrial Research awarded him the Shanti Swarup Bhatnagar Prize, one of the highest Indian science awards in 1974.[26] Sinha received the Award for excellence in Physics of Maharishi University of Management in 1975 and H. H. Wills Physics Laboratory of University of Bristol honored him with the Distinguished Alumnus Award in 1977.[2] The elected fellowships of the Indian National Science Academy and the National Academy of Sciences, India reached him in 1979[27] and 1982 respectively.[28] Two years later, Sinha received the Platinum Jubilee Distinguished Alumnus Award of the Indian Institute of Science.[3]World Who's Who in Science from Antiquity to the Present has been featuring Sinha since its 1976-77 edition.[2]
