Arnold Kosevich

Arnold M. Kosevich (Russian: Арнольд Маркович Косевич Arnoľd Markovič Kosevič, Ukrainian: Косевич Kosevyč; July 7, 1928 – October 3, 2006) was a Soviet Ukrainian physicist, known for contributions to the electron theory of metals and the theory of crystals.

Arnold Kosevich was born in Tulchyn, Ukraine. He graduated from Kharkiv University in 1951, and received his PhD in 1954 under the supervision of Ilya Lifshitz. In 1954–1957 he worked at Chernivtsi University, in 1957-1974 at the Kharkiv Institute of Physics and Technology. In the years 1974–2003 he headed the department of theoretical physics at the B Verkin Institute for Low Temperature Physics and Engineering.

In 1990 he was elected corresponding member of the National Academy of Sciences of Ukraine. He was twice awarded with the State Prizes of Ukraine (1978, 2001). In 1999 he received the Sinelnikov Prize of the National Academy of Sciences of Ukraine. In 2004 he was awarded the title of Doctor (honoris causa) of Kharkiv National University.

Arnold Kosevich worked on the theoretical researches of electronic properties of metals, mechanics of real crystals and magnetoordered systems, and nonlinear dynamics of the condensed media. Together with I. M. Lifshitz, he established (1954) the connection between the oscillation of magnetic characteristics of metals and the form of an electronic surface of Fermi (now called the Lifshitz–Kosevich formula). In 1953 he discovered the phenomenon of quantum dimensional effect in conducting films (the invention was registered in 1977).
