Arkady Aleksandrovich Tseytlin (Аркадий Александрович Цейтлин; born August 31, 1956, in Moscow) is a Soviet, Russian, and British theoretical physicist.
[3][4] He also constructed, jointly with Ruslan Romanovich Metsaev, a superstring action in anti-de Sitter space, which plays a central role in the duality between gauge fields and strings and underlies the exact solution of N=4 supersymmetric Yang-Mills theory based on integrability.
[5] During the 1980s, Yuri Golfand expressed keen interest in the research of Tseytlin and Fradkin.
[7][8] In 2011, Tseytlin was awarded the John William Strutt, Lord Rayleigh Medal and Prize of the UK-based Institute of Physics.
In 2023 he was awarded the Pomeranchuk Prize of the Institute for Theoretical and Experimental Physics (ITEP) from Moscow.
