Alexei Mikhaylovich Tsvelik (ru|Алексей Михайлович Цвелик) is a theoretical condensed matter physicist working on strongly correlated electron systems. He is widely recognised for his pioneering contributions to the theory of low-dimensional systems, including applications of non-perturbative quantum field theory methods and the Bethe Ansatz.
He graduated from the Moscow Physical Technical Institute in 1977,before gaining his PhD in Theoretical Physics in 1980 from theKurchatov Institute for Atomic Energy. Between 1982 and 1989 he workedat the Landau Institute for Theoretical Physics. After visitingpositions at Harvard, Princeton and the University of Florida, Tsvelikwas appointed as a Lecturer, and subsequently Professor,[2] at theUniversity of Oxford (where he was affiliated to Brasenose College). In 2001 he was appointed as a SeniorPhysicist and Group Leader at Brookhaven National Laboratory. He has also served as an adjunct professor of physics at Stony Brook University.
Tsvelik has published more than 240 papers in refereed journals and is theauthor of two textbooks[3] [4] and several books on popular science.[5]
