Russian theoretical physicist. A
student of Lev Landau, Dzyaloshinskii
pursued graduate studies at the
Institute for Physical Problems. He
completed his candidate’s dissertation
in 1957, on the subject of weak
ferromagnetism. He then worked on field
theory, Feynman diagrams,
superconductivity, and often carried
out approximations of the
renormalization group by summing
diagrams. With Lev
Petrovich Gor’kov and Alexei Abrikosov,
from 1958 to 1961, Dzyaloshinski
ascertained ways to apply quantum field
methods to statistical physics. They
published a pioneering and influential
textbook in 1961, Methods of Quantum
Field Theory in Statistical Physics
(the English edition was published in
1963). Dzyaloshinskii specialized in
condensed matter physics. He became a
founding member of the Landau Institute
for Theoretical Physics in Moscow, with
the aim of training graduate students.
With several colleagues, he
analyzed magnetic phase transitions,
crystallization, and quasi
onedimensional systems. He conjectured
that there are cases of phase
transitions where there are no fixed
points. He also helped reformulate the
work of Matsubara. He has
developed diagrammatic techniques for
evaluating transport coefficients at
finite temperatures.
Igor E.
Dzyaloshinski has been a
Professor of Physics at the
University of California at Irvine
since
1992.
