Evgeny Lifshitz

Evgeny Lifshitz was a preeminent Soviet theoretical physicist and a key collaborator of Lev Landau. He is best known as the co-author of the monumental ten-volume Course of Theoretical Physics, a foundational text for generations of physicists worldwide. His own research made profound contributions to general relativity, cosmology, and the theory of condensed matter physics.

Biography

Evgeny Mikhailovich Lifshitz was born in Kharkiv, then part of the Russian Empire, and began his higher education at Kharkiv University. His exceptional talent was quickly recognized by Lev Landau, who became his mentor and later his principal collaborator. Following World War II, he moved to Moscow, where he worked at the prestigious Institute for Physical Problems and also held a professorship at Moscow State University. Throughout his career, he navigated the complex political landscape of the Soviet Union, maintaining a focus on fundamental science. He remained active in research and teaching until his death in Moscow.

Scientific contributions

Lifshitz made seminal contributions across several domains of theoretical physics. In general relativity, he co-developed the BKL singularity with Vladimir Belinski and Isaak Khalatnikov, proposing a chaotic oscillatory model for the universe's behavior near the Big Bang. His work in cosmology included foundational studies on the theory of cosmic inflation and the generation of gravitational waves. In condensed matter, he formulated the Lifshitz transition, a key concept in the electronic structure of metals. He also made significant advances in the theory of molecular forces, leading to the description of the Casimir effect and van der Waals force in complex geometries.

Landau–Lifshitz collaboration

The partnership with Lev Landau was one of the most productive in twentieth-century science, fundamentally shaped by Landau's rigorous theoretical framework. Their most famous joint project was the comprehensive Course of Theoretical Physics, a series designed to cover the entire discipline from classical mechanics to quantum electrodynamics. Following Landau's severe injury in a 1962 car accident, Lifshitz assumed primary responsibility for completing and updating the series. Their collaboration also produced the Landau–Lifshitz equation, a fundamental equation describing the dynamics of magnetic moments in ferromagnetism, and the Landau–Lifshitz–Gilbert equation, its extended form incorporating damping.

Awards and honors

For his scientific achievements, Lifshitz received the highest accolades of the Soviet Union. He was awarded the Stalin Prize in 1954 and the Lenin Prize in 1962, both for his contributions to the Course of Theoretical Physics. He was elected a corresponding member of the Academy of Sciences of the Soviet Union in 1966, becoming a full academician in 1979. His international recognition was solidified by his election as a Foreign Member of the Royal Society in 1982. The Lifshitz Point in statistical physics and the Lifshitz Institute in Kharkiv are named in his honor.

Legacy

Evgeny Lifshitz's legacy is indelibly linked to the educational canon of modern physics through the enduring Course of Theoretical Physics, which remains a standard reference. His original research continues to influence fields from cosmology to condensed matter theory, with concepts like the BKL singularity and Lifshitz transition actively studied. As a pillar of the Soviet school of physics, he helped train and inspire subsequent generations of theorists. His work exemplifies the profound impact of collaborative scientific endeavor and rigorous theoretical exposition.
