Ilya Mikhailovich Lifshitz (Russian: Илья́ Миха́йлович Ли́фшиц; January 13, 1917 – October 23, 1982) was a leading Soviet theoretical physicist, brother of Evgeny Lifshitz. He is known for his works in solid state physics, electron theory of metals, , and the theory of polymers.[1][2]

Work[]

Together with Arnold Kosevich, Lifshitz established (1954) connection between the oscillation of magnetic characteristics of metals and the form of an electronic surface of Fermi () from de Haas–van Alphen experiments.

Lifshitz was one of the founders of the theory of disordered systems.[3] He introduced some of the basic notions, such as self-averaging, and discovered what is now called and .

In perturbation theory, Lifshitz introduced[4] the notion of , which was later developed by Mark Krein.

Starting from the late 1960-s, Lifshitz started considering problems of statistical physics of polymers. Together with his students Alexander Yu. Grosberg and Alexei R. Khokhlov, Lifshitz proposed a theory of coil-to-globule transition in homopolymers and derived the formula for the conformational entropy of a polymer chain (that is also referred to as Lifshitz entropy).[5]
