Igor Ekhielevich Dzyaloshinskii, (Игорь Ехиельевич Дзялошинский, surname sometimes transliterated as Dzyaloshinsky, Dzyaloshinski, Dzyaloshinskiĭ, or Dzyaloshinkiy, 1 February 1931 – 14 July 2021)[1] was a Russian theoretical physicist, known for his research on "magnetism, multiferroics, one-dimensional conductors, liquid crystals, van der Waals forces, and applications of methods of quantum field theory".
His father, Yechiel Moiseevich Dzyaloshinskii (1897–1942), a native of Kalush, Ukraine, died in captivity in early 1942.
His Russian doctoral thesis dealt with application of quantum field theory methods in statistical physics.
Dzaloshinskii did important research with Lev Pitaevskii in solving "the problem of the van der Waals forces between bodies separated by an absorbing liquid" and with Yury Bychkov and Lev Gor’kov on the "problem of superconducting and charge-density-wave instabilities in 1D conductors".
[2] Dzyaloshinskii and Anatoly Larkin in the 1970s published "a solution to the Luttinger-liquid problem that is central to the theory of 1D Fermi systems and to the bosonization technique.
