Isaak Khalatnikov
Isaak Markovich Khalatnikov was a Soviet and Russian theoretical physicist who has made significant contributions to many areas of theoretical physics, including general relativity, quantum field theory, as well as the theory of quantum liquids. He is well known for his role in developing the Landau-Khalatnikov theory of superfluidity and the so-called BKL conjecture in the general theory of relativity.
Isaak Pomeranchuk
Isaak Yakovlevich Pomeranchuk was a Soviet theoretical physicist working in particle physics, quantum field theory, electromagnetic and synchrotron radiation, condensed matter physics and the physics of liquid helium. The Pomeranchuk instability, the pomeron, and a few other phenomena in particle and condensed matter physics are named after him.
