Sergei Vladimirovich Tyablikov (Russian: Серге́й Влади́мирович Тя́бликов; September 7, 1921 – March 17, 1968) was a Russian theoretical physicist known for his significant contributions to statistical mechanics, solid-state physics, and for the development of the double-time Green function's formalism.
Tyablikov was born in Klin, Russia. In 1944 he graduated from the Faculty of Physics at the Moscow State University (MSU) and started his postgraduate study with Anatoly Vlasov and later with Nikolay Bogoliubov at the Department of Theoretical Physics. In 1947 he obtained PhD degree (Candidate of Sciences) with PhD Thesis on the subject of crystallization theory and was appointed to the Steklov Institute of Mathematics, where he continued to work for the rest of his life.
In 1954 he defended at the MSU his doctoral dissertation "Studies of the Polaron Theory" and obtained the degree of Doktor nauk (Doctor of Science, similar to Habilitation). Since 1962 he was the Head of the Division of Statistical Mechanics in the Steklov Institute of Mathematics.
In the period 1966-1968, Sergei Tyablikov also worked at the Joint Institute for Nuclear Research, where he was the first Head of the Statistical Mechanics and Theory of Condensed Matter Group at the Laboratory of Theoretical Physics.
During postgraduate study in 1944—1947 he worked on theory of crystallization, where he applied such methods as diagonalization of bilinear forms in Bose or Fermi operators, etc., which later became a common tool for theoretical physicists.
