Dmitri Dmitrievich Ivanenko (Ukrainian: Дмитро́ Дми́трович Іване́нко, Russian: Дми́трий Дми́триевич Иване́нко; July 29, 1904 – December 30, 1994) was a Soviet theoretical physicist of Ukrainian origin who made great contributions to the physical science of the twentieth century, especially to nuclear physics, field theory, and gravitation theory.
In 1926, while still a student, he wrote his first scientific works: with George Gamow on the Kaluza–Klein five-dimensional theory and with Lev Landau on the problems of relativistic quantum mechanics.
After graduating from the university, from 1927 to 1930 D. Ivanenko was a scholarship student and then a research scientist at the Physical Mathematical Institute of Academy of Sciences of the USSR.
In 1930, Ambartsumian and Ivanenko suggested the hypothesis of creation of massive particles (1930) which is a cornerstone of contemporary quantum field theory.
In 1934 D. Ivanenko and I. Tamm laid the basis of the first non-phenomenological theory of paired electron-neutron nuclear forces.
In this period, Ivanenko's scientific interest gradually shifted from nuclear physics to cosmic ray theory.
From 1943 and until the last days of his life, Professor Ivanenko was closely associated with the physics faculty of M. V. Lomonosov Moscow State University.
The discovery of synchrotron radiation opened a new and important chapter in modern physics as a result of its special properties and possible applications.
Classical and quantum theory of synchrotron radiation was developed in research performed by students and followers of D. D. Ivanenko: A.
In the 1960s, D. Ivanenko did intensive scientific, scientific-methodological, and organizational work on the development and coordination of gravitation research in USSR.
At the beginning of the 1960s D. D. Ivanenko was the organizer of the gravitation section of Ministry of Higher Institutes of Learning of the USSR, which lasted until the 1980s.
