Lev Davidovich Landau (Russian: Ле́в Дави́дович Ланда́у; January 22 [O.S. January 9] 1908 – April 1, 1968) was a prominent Soviet physicist who made fundamental contributions to many areas of theoretical physics. His accomplishments include the independent co-discovery of the density matrix method[1] in quantum mechanics (alongside John von Neumann), the quantum mechanical theory of diamagnetism, the theory of superfluidity, the theory of second-order phase transitions, the Ginzburg–Landau theory of superconductivity, the theory of Fermi liquid, the explanation of Landau damping in plasma physics, the Landau pole in quantum electrodynamics, and the two-component theory of neutrinos. He received the 1962 Nobel Prize in Physics for his development of a mathematical theory of superfluidity that accounts for the properties of liquid helium II at a temperature below 2.17 K (−270.98 °C).

Early years

Landau family in 1910

Landau was born on January 22, 1908 to Jewish parents[2][3][4] in Baku, in what was then the Russian Empire. Landau's father was an engineer with the local oil industry and his mother was a doctor. Recognized very early as a child prodigy in mathematics, Landau was quoted as saying in later life that he scarcely remembered a time when he was not familiar with calculus. Landau graduated at 13 from gymnasium. His parents considered him too young to attend university, so for a year he attended the Baku Economical Technicum. In 1922, at age 14, he matriculated at Baku State University, studying in two departments simultaneously: the department of Physics and Mathematics, and the department of Chemistry. Subsequently he ceased studying chemistry, but remained interested in the field throughout his life.

In 1924, he moved to the main centre of Soviet physics at the time: the Physics Department of Leningrad State University. In Leningrad, he first made the acquaintance of genuine theoretical physics and dedicated himself fully to its study, graduating in 1927. Landau subsequently enrolled for post-graduate study at the Leningrad Physico-Technical Institute, and at 21, received a doctorate. Landau got his first chance to travel abroad in 1929, on a Soviet government traveling fellowship supplemented by a Rockefeller Foundation fellowship.

After brief stays in Göttingen and Leipzig, he went to Copenhagen to work at Niels Bohr's Institute for Theoretical Physics. After the visit, Landau always considered himself a pupil of Niels Bohr and Landau's approach to physics was greatly influenced by Bohr. After his stay in Copenhagen, he visited Cambridge and Zürich before returning to the Soviet Union.

Kharkov

Between 1932 and 1937 he headed the department of theoretical physics at the Kharkov Polytechnical Institute. Apart from his theoretical accomplishments, Landau was the principal founder of a great tradition of theoretical physics in Kharkov, Soviet Union, sometimes referred to as the "Landau school". In Kharkov, he and his friend and former student, Evgeny Lifshitz, began writing the Course of Theoretical Physics, ten volumes that together span the whole of the subject and are still widely used as graduate-level physics texts. During the Great Purge, Landau was investigated within the UPTI Affair in Kharkov, but he managed to leave for Moscow to take up a new post.[5]

Landau developed a comprehensive exam called the "Theoretical Minimum" which students were expected to pass before admission to the school. The exam covered all aspects of theoretical physics, and between 1934 and 1961 only 43 candidates passed.

Institute for Physical Problems, Moscow

Landau was the head of the Theoretical Division at the Institute for Physical Problems from 1937 until 1962.[6] Landau was arrested on April 27, 1938, because he had compared the Stalinist dictatorship with that of Hitler,[5][7] and was held in the NKVD's Lubyanka prison until his release on April 29, 1939, after the head of the institute Pyotr Kapitsa, an experimental low-temperature physicist, wrote a letter to Joseph Stalin, personally vouching for Landau's behavior, and threatening to quit the institute if Landau were not released.[8] After his release Landau discovered how to explain Kapitza's superfluidity using sound waves, or phonons, and a new excitation called a roton.[5]

Landau led a team of mathematicians supporting Soviet atomic and hydrogen bomb development. Landau calculated the dynamics of the first Soviet thermonuclear bomb, including predicting the yield. For this work he received the Stalin Prize in 1949 and 1953, and was awarded the title "Hero of Socialist Labor" in 1954.[5]

His students included Lev Pitaevskii, Alexei Abrikosov, Arkady Levanyuk, Evgeny Lifshitz, Lev Gor'kov, Isaak Khalatnikov, Boris L. Ioffe, Roald Sagdeev and Isaak Pomeranchuk.

Family

In 1937 Landau married a girl from Kharkov, Kora T. Drobanzeva;[9] their son Igor was born in 1946. Landau believed in free love rather than monogamy, and encouraged his wife and his students to practice free love; his wife was not enthusiastic.[5]

Last years

On January 7, 1962, Landau's car collided with an oncoming truck. He was severely injured and spent two months in a coma. Although Landau recovered in many ways, his scientific creativity was destroyed,[6] and he never returned fully to scientific work. His injuries prevented him from accepting the 1962 Nobel Prize for physics in person.[10]

In 1965 former students and coworkers of Landau founded the Landau Institute for Theoretical Physics, located in the town of Chernogolovka near Moscow, and headed for the following three decades by Isaak Markovich Khalatnikov.

In June 1965, Lev Landau and Yevsei Liberman published a letter in the New York Times, stating that as Soviet Jews they opposed US intervention on behalf of the Student Struggle for Soviet Jewry.[11]

Death

Landau died on April 1, 1968, aged 60, from complications of the injuries sustained in the car accident he was involved in 6 years earlier. He was buried at Novodevichy cemetery.[12][13]

Legacy

Two celestial objects are named in his honor:

Landau's List

Landau kept a list of names of physicists which he ranked on a logarithmic scale of productivity ranging from 0 to 5. The highest ranking, 0.5, was assigned to Albert Einstein. A rank of 1 was awarded to "historical giants" Isaac Newton, Eugene Wigner, and the founding fathers of quantum mechanics, Niels Bohr, Werner Heisenberg, Paul Dirac and Erwin Schrödinger. Landau ranked himself as a 2.5 but later promoted himself to a 2. David Mermin, writing about Landau, referred to the scale, and ranked himself in the fourth division, in the article My Life with Landau: Homage of a 4.5 to a 2.[15][16]

Books about Landau

In popular culture

  • Russian television film My Husband – the Genius (unofficial translation of the Russian title Мой муж — гений) released in 2008 tells biography of Landau (played by Daniil Spivakovsky), mostly relying on his private life. It was generally panned by critics. People who had personally met Landau, including famous Russian scientist Vitaly Ginzburg, said that the film was not only terrible but also false in historical facts.
  • Another film about Landau, Dau, is in the filming process now and was originally planned to be released in 2010. It is directed by Ilya Khrzhanovsky with non-professional actor Theodor Kurentzis (an orchestra conductor) as Landau.
