Krori-Barua Solution

Kamalendu Deb Krori (born 21 January 1930) is an Indian theoretical physicist and the former Principal of Cutton College.[1]

He pioneered research on general relativity in the North Eastern region of India and guided 16 scholars for their Ph.D degrees.[2][3] He has co-authored almost 150 peer-reviewed research papers in International Journals. He is known for the “Krori-Barua Solution”[4][5] a general relativistic solution for a singularity free charged fluid sphere (1975) ; the pertinent paper has more than 150 citations. In 1982, Krori along with two students showed why the elusive fundamental particles neutrinos, originally believed to be mass-less like the photons, must possess some finite rest mass in order to be consistent with Einstein’s general theory of relativity.

In 1998, the Japanese Super-Kamiokande experiment confirmed that neutrinos indeed possess tiny masses by confirming existence of neutrino oscillations by which neutrinos change their flavours during their long cosmic journeys.

Education and career[edit]

Krori received a BSc degree from Karimganj College and M.Sc from Calcutta University[6] in 1953.

Krori joined Karimganj College and then Cutton College as a lecturer.[6] He became a professor at St. Anthony's College, Shillong.[6] After holding many teaching positions, he earned Ph.D. degree by virtue of independent research in theoretical physics from Jadavpur University, Kolkata, in 1971. He joined Cotton College, Guwahati, in north-east India, as a lecturer in physics. There he started research on the general theory of relativity. Later he became a full professor and headed the Department of Physics. He became the Principal of the institute in 1987 and retired in 1991.

Honours and recognition[edit]

Krori has received awards including:[7]

  • Dr. H. C. Bhuyan award in Physical Sciences by Assam Science Society in 1990.
  • Emeritus Fellowship by University Grants Commission, in Physics (1991-1993).
  • National Teacher Award in 2010 from K.C. Das Commerce College.
  • Vaidya Roychoudhury Award, 2020.[8]
  • Member, New York Academy of Sciences, New York (USA).
