Evgeny Lifshitz
Evgeny Mikhailovich Lifshitz entered the world on the 21st of February 1915. He was born into a Jewish family in Kharkov, then part of the Russian Empire. This city now bears the name Kharkiv and sits within modern Ukraine. His brother Ilya would also become a noted physicist. The early years unfolded during a time of great political upheaval across the Soviet Union. Lifshitz began his academic journey within this turbulent environment. He pursued studies that would eventually lead him to the forefront of theoretical physics.
Lev Landau created an examination designed to test the deepest understanding of theoretical physics. Only 43 people ever passed this rigorous assessment throughout history. Lifshitz stood as the second individual among those few who succeeded. The exam served as a filter for identifying true masters of the field. It required candidates to demonstrate mastery over complex mathematical frameworks. Fewer than fifty physicists achieved this distinction before Lifshitz's death in 1985. The scarcity of successful examinees highlighted the extreme difficulty of the task.
Lifshitz collaborated with Lev Landau to produce a series of graduate-level textbooks. They titled their work Course of Theoretical Physics. These volumes aimed to introduce students to the entire breadth of physics. The books remain widely used by scholars decades after their initial publication. Authors suggested corrections to the standard periodic table regarding lutetium placement. Later findings vindicated their claim that lutetium belongs to the d-block. The International Union of Pure and Applied Chemistry endorsed this view in 1988. The series continues to serve as an invaluable resource for modern physicists.
The physicist co-authored research concerning generic curvature singularities with Vladimir Belinski and Isaak Khalatnikov. This collaborative effort became known as the BKL conjecture. Scientists regard this work as one of the most important open problems in classical gravitation. Their paper explored the nature of spacetime near such singularities. The study remains central to discussions about black holes and cosmology today. Lifshitz contributed his mathematical expertise to solve these complex equations. The conjecture has influenced generations of researchers studying gravitational collapse.
Evgeny Lifshitz made significant contributions to quantum electrodynamics through specific calculations. He determined the Casimir force acting on arbitrary macroscopic configurations. His work covered systems involving metals and dielectrics arranged in various shapes. These formulas allowed scientists to predict forces between objects at microscopic scales. The results provided a foundation for understanding interactions in condensed matter physics. Lifshitz derived expressions that applied to real-world materials rather than idealized models. His approach bridged theoretical concepts with practical experimental observations.
A special multicritical point carries the name of Evgeny Lifshitz since 1975. This concept describes a unique state where multiple phase transitions meet simultaneously. Researchers use the term Lifshitz point to identify conditions in magnetic and liquid crystal systems. The discovery emerged from studies of how materials behave under varying temperatures and pressures. It represents a critical juncture in the phase diagram of certain substances. Scientists continue to apply this framework when analyzing complex material behaviors. The naming honored his lasting impact on statistical mechanics and thermodynamics.
