Gerasim Eliashberg

Gerasim Eliashberg was a prominent Soviet theoretical physicist, born in 1930, who made significant contributions to the field of physics. His work primarily focused on condensed matter physics, and he is renowned for developing the Eliashberg theory. This theory serves as a microscopic extension of the Bardeen–Cooper–Schrieffer theory, which explains the phenomenon of superconductivity.

Eliashberg's research also explored other areas, including Landau's Fermi-liquid theory and nonequilibrium superconductivity. His work in these fields has had a lasting impact on the understanding of superconductivity and condensed matter physics. Throughout his career, Eliashberg demonstrated a deep understanding of complex physical phenomena, and his theories continue to be relevant in the field of physics. He passed away in 2021, leaving behind a legacy of important contributions to the world of theoretical physics.
