Elepter Andronikashvili

Elephter Luarsabovich Andronikashvili (the first name sometimes spelled Elevter or Elefter, Georgian: ელეფთერ ანდრონიკაშვილი, Russian: Элевтер Луарсабович Андроникашвили; 25 December [O.S. 12 December] 1910 – 9 September 1989) was a Georgian physicist. He was a brother of Russian historian Irakly Andronikov.

Elepter came from a noble Georgian Andronikashvili family. Andronikashvilily graduated from Leningrad Polytechnical Institute in 1932. In 1934 - 1945 he lectured in Tbilisi State University. Since 1942 he worked for the Georgian Academy of Sciences Institute of Physics, since 1951 he is the director of the Institute. In 1940-1941 and 1945-1948 he also did his Doktor Nauk degree at the Institute for Physical Problems in Moscow. Since 1951 he also worked as a head of a department and a Professor of Tbilisi State University.

Andronikashvili received Stalin Prize in 1952 for his works on superfluidity and USSR State Prize in 1978. Andronikashvili was a full member of the Georgian Academy of Sciences (since 1955).

Andronikashvili conducted early experiments on superfluid helium II, including the classic experiment in 1946, suggested by the Russian theorist Lev Landau, studying the period and damping of torsional oscillations of stacked closely spaced rotating disks. This provided key evidence to help establish the two fluid model of superfluidity.
