21st-century Russian physicists

The 21st century has seen significant contributions from Russian physicists across various fields of physics, including condensed matter physics, quantum mechanics, astrophysics, and particle physics. Some notable Russian physicists and their areas of work include: 1. **Alexei Abrikosov** - Known for his work on superconductivity and magnetic flux in superconductors, he was awarded the Nobel Prize in Physics in 2003.

As of my last knowledge update in October 2023, Alexander Pechen does not appear to be a widely recognized public figure, historical person, or concept that is well-documented in accessible sources. It's possible that he could be an emerging figure in a specific field, a private individual, or a fictional character.

Maxim Chernodub is a physicist known for his work in the fields of condensed matter physics, particularly in relation to phenomena such as superconductivity, quantum materials, and the theoretical aspects of these areas. His research often explores the interplay between topology and quantum mechanics in solid-state systems.

Pavel Belov is a physicist known for his work in the fields of nanophotonics and metamaterials. His research often focuses on manipulating light at the nanoscale using artificial structures to create novel optical effects. Belov's work contributes to the development of new materials and devices that can control electromagnetic waves, which has applications in optics, telecommunications, and various technologies related to imaging and sensing.

Vladimir Lipunov is a Russian astrophysicist known for his work in the field of gamma-ray bursts, gravitational waves, and the study of transients in the universe. He has made significant contributions to the understanding of explosive astrophysical phenomena, including supernovae and other transient events. In addition to his research, Lipunov is also involved in education and outreach in astronomy and has authored numerous publications in scientific journals.
