'''Madan Lal Mehta''' (1932–2006) was an Indian [[theoretical physicist]], particularly known for his work in [[random matrix theory]].<ref>{{cite web |archive-url=https://web.archive.org/web/20110720210305/http://ipht.cea.fr/en/Phocea-SPhT/ast_visu_spht.php?id_ast=447 |archive-date=2011-07-20 |url-status=dead |title=Madan Lal MEHTA (1932-2006) |url=http://ipht.cea.fr/en/Phocea-SPhT/ast_visu_spht.php?id_ast=447 |publisher=[[Institut de physique théorique - IPhT Saclay]] |website=[[IPHT.cea.fr]]}}</ref><br />
<br />
==Biography==<br />
Madan Lal Mehta was born on 24 December 1932 in Relmagra, [[Rajasthan]], a small village near [[Udaipur]] in northwest India. He obtained his Master of Science in Mathematics from the [[University of Rajasthan]] ([[Jaipur]]) in 1956.<br />
<br />
After two years at the [[Tata Institute of Fundamental Research]] in [[Bombay]], he went to France in November 1958 to join the Department of Mathematical Physics (now the Department <br />
of Theoretical Physics) at [[CEA Saclay|Centre d'Etudes Nucléaires de Saclay]].<br />
<br />
In 1961, he received his PhD under [[Claude Bloch]] working on materials at low density. From 1962 to 1963, he worked at the [[Institute for Advanced Study]] in [[Princeton University|Princeton]] (USA).<br />
<br />
He then returned to India, working at [[Delhi University]], before returning to the United States from 1966–1967 to work at Princeton University and [[Argonne National Laboratory]]. Later, Mehta moved to the Department of Theoretical Physics at CEA Saclay in September 1967, where he remained until the end of his academic career. As [[CNRS]] hired him in 1970, Mehta acquired French citizenship in 1971.<br />
<br />
After his career at CEA Saclay, he returned to India in January 2005 and died on 10 December 2006, in Udaipur. Mehta spoke several languages, including English, French, Russian, Japanese, Mandarin and Hindi.<br />
<br />
==Work in physics==<br />
<br />
Madan Lal Mehta is known for his work on [[random matrix|random matrices]]. His book "Random Matrices" is considered classic in the field.<ref>{{cite book|last=Mehta|first=M.L.|title=Random Matrices|publisher=Elsevier/Academic Press|location=Amsterdam|year=2004|edition=3rd|isbn=0-12-088409-7}}</ref><ref>{{cite book|last=Mehta|first=Madan Lal|title=Random Matrices, Volume 142, Third Edition (Pure and Applied Mathematics)|year=2004|publisher=[[Academic Press]]|isbn=978-0120884094}}</ref> [[Eugene Wigner]] cited Mehta during his SIAM review on Random Matrices.<ref>{{Cite journal|url=https://doi.org/10.1137/1009001|doi=10.1137/1009001|title=Random Matrices in Physics|year=1967|last1=Wigner|first1=Eugene P.|journal=SIAM Review|volume=9|pages=1–23|url-access=subscription}}</ref> Physicist [[Freeman Dyson]] recommended Mehta's book to mathematician [[Hugh Lowell Montgomery|Hugh Montgomery]], to perhaps explain the pair correlation Montgomery had found between the zeroes of the Riemann zeta function.<ref name="Thomas 2013 Prime Numbers to Nuclear Physics">{{cite web | last=Thomas | first=Kelly Devine | title=From Prime Numbers to Nuclear Physics and Beyond | website=Institute for Advanced Study | date=2013-05-02 | url=https://www.ias.edu/ideas/2013/primes-random-matrices | access-date=2024-01-25}}</ref><br />
<br />
Together with Michel Gaudin, Mehta developed the orthogonal polynomial method, a basic tool to study the eigenvalue distribution of invariant matrix ensembles. Together with [[Freeman Dyson]], Mehta worked on Dyson's [[circular ensemble]]s. Other well-known collaborators include P.K. Srivastava, N. Rozenzweig, J. of Cloizeaux, G. Mahoux, A. Pandey, Pragya Shukla, J.M. Normand, I. Kostov and B. Eynard.<br />
