Alexander Borissowitsch Samolodchikow
Alexander Borissowitsch Samolodtschikow ( Russian Александр Борисович Замолодчиков , English translation Zamolodchikov ; born September 18, 1952 in Dubna ) is a Russian theoretical physicist working in the USA .
Samolodchikow studied nuclear engineering at the Moscow Institute of Physics and Technology , where he graduated in 1975 as an engineer. In 1978 he received his doctorate at the Institute for Theoretical and Experimental Physics in Moscow. From 1978 he was a professor at the Landau Institute in Chernogolowka . Since 1990 Samolodchikow has been a professor of physics at Rutgers University . He is best known for his fundamental pioneering work on conformal field theories with Alexander Polyakov and Alexander Belawin . With Wadim Genrichowitsch Knischnik , he introduced the concentration camp equations named after them into conformal field theory.
In 1986 he proved his c-theorem, which ensures the existence of a monotonically decreasing function in two dimensions with the flow of the renormalization group (RG) (a function of the coupling constants and energy scale), which is constant at the fixed points of the RG (which correspond to conforming field theories ), assumes values independent of the energy scale (the central charges of conformal field theories). A generalization of the theorem to four dimensions comes from John Cardy and was proven in 2011 by Zohar Komargodski and Adam Schwimmer . For solid-state physics a similar theorem for three dimensions (two space, one time dimension) would be of interest, but the problem is open for odd-numbered dimensions.
In 1999 he received the Dannie Heineman Prize for Mathematical Physics , the Humboldt Research Prize in 2003 and the Dirac Medal (ICTP) in 2011 with Édouard Brézin and John Cardy . Also in 2011 he received the Lars Onsager Prize with Sascha Belawin and Alexander Polyakov . In 1999 he became a Fellow of the American Physical Society . In 2012 Somolodchikov was elected to the American Academy of Arts and Sciences , and in 2016 to the National Academy of Sciences . For 2014 he was awarded the Pomeranchuk Prize .
His twin brother Alexei Samolodtschikow (1952-2007) was also a theoretical physicist.
