Igor Dzyaloshinsky

Igor Ekhielevich Dzyaloshinskii, (Игорь Ехиельевич Дзялошинский, surname sometimes transliterated as Dzyaloshinsky, Dzyaloshinski, Dzyaloshinskiĭ, or Dzyaloshinkiy, 1February 193114July 2021) 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". In particular he is known for the Dzyaloshinskii–Moriya interaction.

Biography He was born in Moscow to a Jewish family. His father, Yechiel Moiseevich Dzyaloshinskii (1897–1942), a native of Kalush, Ukraine, died in captivity in early 1942.

The first in his family to attend a university, Weak ferromagnetism is "a small spontaneous magnetic moment in certain classes of antiferromagnetic materials". Its explanation involves exchange interactions based upon "concepts of the magnetic symmetry of crystals".

In 1962 Dzyaloshinskii received his Russian Doctor of Sciences degree (habilitation). His Russian doctoral thesis dealt with application of quantum field theory methods in statistical physics. and from 1972 to 1989 at Moscow State University.

In 1991 he immigrated to the United States and soon became a professor at the University of California, Irvine (UCI), where he eventually retired as professor emeritus.

Dzyaloshinskii applied diagram methods to finite-temperature transport problems. He conjectured the existence of phase transitions without fixed points of the renormalization group. He was involved in the formulation of the Matsubara formalism (Takeo Matsubara, 1955).

Dzyaloshinskii was awarded in 1972 the Lomonosov Prize, in 1975 the Order of the Badge of Honour, in 1981 the Order of the Red Banner of Labour, in 1984 the USSR State Prize, and in 1989 the Landau Prize. He was elected in 1974 a corresponding member of the Soviet Academy of Sciences, in 1991 an honorary foreign member of the American Academy of Arts & Sciences, in 1996 a fellow of the American Physical Society, and in 2002 a fellow of the American Association for the Advancement of Science.

He married in 1960.
