Anatoly Ivanovich Larkin (Russian: Анатолий Иванович Ларкин; October 14, 1932 – August 4, 2005) was a Russian theoretical physicist, universally recognised as a leader in theory of condensed matter, and who was also a celebrated teacher of several generations of theorists.
He worked on his PhD on the properties of plasmas under the supervision of A.B.Migdal and later received the degree of Doctor of Science (1965) for studies of superconductivity.
The dominant part of his work is devoted to superconductivity, magnetism, ferro-electricity, properties of metals, semiconductors and dielectrics.
He pioneered the concept of spontaneous symmetry breaking in the physics of elementary particles,[4] discovered collective pinning of magnetic flux in superconductors,[5] predicted paraconductivity[6] and effects of fluctuations on properties of superconductors,[7] made essential contributions to the theory of weak localization,[8] as well as developed the concept of the Ehrenfest time[9] and its effect on phenomena of quantum chaos.
His students and collaborators are teaching and conducting research in Russia, USA, Great Britain, France, Italy, Germany, Switzerland, Israel and other countries.
