Chanchal Kumar Majumdar (Bengali:

S.N. Bose National Centre for Basic Sciences. Known for his research in quantum mechanics, Majumdar was an elected fellow of all the three major Indian science academies – the Indian National Science Academy, the National Academy of Sciences, India, and the Indian Academy of Sciences – as well a member of the New York Academy of Sciences and the American Physical Society
.

Majumdar was the mentor of

Nobel laureates. The Council of Scientific and Industrial Research, the apex agency of the Government of India for scientific research, awarded him the Shanti Swarup Bhatnagar Prize for Science and Technology
, one of the highest Indian science awards, for his contributions to Physical Sciences in 1976.

Biography

Presidency College, a Francis Frith image

C. K. Majumdar was born on 11 August 1938 in

Rajabazar Science College, University of Calcutta.[2]

After undertaking postgraduate research at the

Nobel Prize for Physics in 1963, earned him a PhD in 1965, and he did his post-doctoral work at Carnegie Mellon University (then known as Carnegie Institute of Technology) while continuing his work with Kohn for a while.[4]

On his return to India in 1966, Majumdar joined the Tata Institute of Fundamental Research as an associate professor, where he stayed until his move to University of Calcutta in 1975.[5] In between, he had a short stint at the University of Manchester in 1969–70, working alongside Sam Edwards.[6]

At Calcutta University, Majumdar served as the Palit Professor of Physics at the

S.N. Bose National Centre for Basic Sciences (SNBNCBS), an autonomous institute for basic research in mathematics, Majumdar was appointed as its first director in 1987.[7] Following a decade of service at SNBNCBS, he retired from official service in 1999.[8]

After retirement from regular service, Majumdar served as a senior scientist of the Indian National Science Academy at the Indian Statistical Institute, but his stint there was short-lived.[7] He succumbed to a heart attack on 20 June 2000 in Kolkata, aged 61.[6] He was survived by his wife, Utpala Ghosh, whom he had married soon after his return from the US in 1968, and their two children, Ruchira and Rupak.[2]

Legacy

An electrostatic analogue for a magnetic moment - Majumdar developed methods for measuring magnetic moments

A major turning point in Majumdar's career came during his doctoral work with Walter Kohn in the early 1960s. The Austrian-born American scientist had already been known in the scientific world for his development of the

Nobel Prize for chemistry[9]), and his association with Majumdar resulted in the development of the Kohn-Majumdar theorem,[10] which explained the continuity in a Fermi gas in relation to its bound and unbound states.[7][11] They described the theorem in an article, Continuity between Bound and Unbound States in a Fermi Gas, published in Physical Review in 1965.[12]

Later, during his days at TIFR, Majumdar guided

finite Heisenberg chains; his work proved that violation of the rules related to non-degeneracy and avoided crossing existed.[15]

Fermi momentum of metals.[17]

His studies have been documented by way of a number of articles[18][note 1] and the article repository of the Indian Academy of Sciences has listed 45 of them.[19] Majumdar also published two books, Annihilation of Positrons in Metals[20] and S N Bose: The Man and His Work,[21] and contributed chapters to books published by others.[22][23][24][25]

On the academic front, Majumdar was instrumental in modernising the physics laboratories at Calcutta University.[1] He was associated with a number of national and international agencies; he was a member of the Indian National Commission for Cooperation with UNESCO and the Indo-US Subcommission in Physics.[5] He sat on the Physics panel of the University Grants Commission as well as the commission on higher education in West Bengal. He served as a member of the advisory committees on Physics of the Department of Science and Technology and the Council of Scientific and Industrial Research. He was the editor of the Indian Journal of Physics and was a member of the editorial board of the Pramana journal. He was associated with the conference on Observational Evidence for Black Holes in the Universe held in Kolkata in 1998 as a member of its scientific advisory committee.[26] He was the president of the Indian Physical Society (1988–90)[5] and the Indian Centre for Space Physics (1999–2000),[27] and served as an executive council member of the Raman Centre for Applied and Interdisciplinary Sciences.[28]

Controversy

Towards the end of his career at S. N. Bose Centre, he faced allegations of misappropriation of funds.[3] His mentor, Walter Kohn, later argued that the allegations stemmed from Majumdar's troubled relationship with trade unions under the influence of the Communist Party of India when the state was run by a Left Front government led by Jyoti Basu.[3]

Awards and honours

The Council of Scientific and Industrial Research awarded Majumdar the

Asiatic Society in 1978 and was selected as a National Lecturer by University Grants Commission (UGC) the same year; the P. A. Pandya Award of the Indian Physics Association reached him a year later.[1] In 1982, the Indian National Science Academy (INSA) elected him as a Fellow,[31] and in 1983 the UGC honoured him again with the Meghnad Saha Award for Research in Theoretical Sciences.[5] He received another honour from INSA by way of the Satyendranath Bose Medal in 1989.[32] He became an elected fellow of the American Physical Society[33] and delivered the Santanu Ghosh Memorial Lecture of the Indian Science News Association, Calcutta, both honours coming in 1991.[34] The Indian Science Congress Association awarded him the Satyendranath Bose Birth Centenary Award in 1997.[1] He was also a fellow of the National Academy of Sciences, India,[35] Indian Physical Society and the New York Academy of Sciences.[5]

The

Daniel I. Khomskii.[36] An issue of Physics Letters B in 2000, the year of his death, was published as a festschrift on him.[37]

To commemorate his 60th birthday, an international conference on statistical physics, Statphys – Calcutta III, was held at S. N. Bose Centre in January 1999.[38][39] A year after his death, the Indian Statistical Institute organised a Workshop on Strongly Correlated Electron Systems to honour his memory.[40]
