January 9 the oldest member of the Russian Academy of Sciences (RAS), the last of the participants in the development of the first Soviet atomic bomb, theoretical physicist Isaak Khalatnikov died at 102nd year of life.
This is reported by the portal “Scientific Russia”. It is known that the academician passed away in Chernogolovka near Moscow, where the Landau Institute for Theoretical Physics (ITP), whose founder he was.
“We mourn the passing of dear Isaak Markovich, a friend of our portal and journal, a friend of our teacher Sergey Petrovich Kapitsa, and express our condolences to his relatives, friends, students, and colleagues,” the message reads.
The TP news agency confirms the news of the academician’s death. The website of the Russian Academy of Sciences says that Khalatnikov took part in the creation of atomic and hydrogen weapons in the USSR.
In addition, he proposed a solution to the difficult problem of stability in the calculation of bombs, which significantly reduced the time required to create charges.
Isaak Khalatnikov was born on October 17, 1919, in Yekaterinoslav (now Dnepropetrovsk, Ukraine). He participated in the Great Patriotic War. After his demobilization, he became a graduate student of Lev Landau.
In the late 1940s and early 1950s, he worked as part of a group of theorists who performed calculations for nuclear and thermonuclear weapons. In 1965-1992, he was the director of the Landau Institute of Theoretical Physics, Russian Academy of Sciences. From 1965 to 1992, he was director of the Landau Institute for Theoretical Physics of the Russian Academy of Sciences. Corresponding member of the USSR Academy of Sciences since 1972, member of the USSR Academy of Sciences since 1984. Foreign Member of the Royal Society of London since 1994. Since August 2020 – the oldest academician of RAS.
For his work on the atomic bomb, he was awarded the Stalin Prize II degree (1953). He was also awarded the Landau Prize of the USSR Academy of Sciences (1974), the Order of Merit for the Fatherland III (1999), and the Order of Alexander Nevsky (2020).
Isaac Khalatnikov is a legendary figure in the scientific world. He was a specialist in the field of low-temperature physics, quantum field theory, relativistic astrophysics, and other fields of theoretical physics.
The academician is the author and co-author of hundreds of scientific works. Together with the theoretical physicist Lev Landau, he developed the theory of quantum liquids and applied it to liquid helium.
