Alexei Abrikosov
Early Life and Education
Alexei Alexeyevich Abrikosov was born on June 25, 1928, in Moscow, Soviet Union. He was the son of Alexey Ivanovich Abrikosov, a prominent pathologist, and Fani Davidovna Wolfson, a biochemist. From an early age, Abrikosov was exposed to a scientific environment, which significantly influenced his future career. He attended Moscow State University, where he completed his undergraduate studies in physics in 1948. He continued his education at the same institution, earning his Ph.D. in 1951 under the supervision of Lev Landau, a renowned theoretical physicist.
Scientific Contributions
Superconductivity
One of Abrikosov's most significant contributions to physics was his work on superconductivity. In 1952, he discovered the phenomenon of type-II superconductors, which are materials that can conduct electricity without resistance at relatively high magnetic fields. This discovery was pivotal in advancing the understanding of superconducting materials and their potential applications. Abrikosov's theoretical work on the Ginzburg-Landau theory of superconductivity provided a comprehensive framework for describing the behavior of superconductors in the presence of magnetic fields.
Quantum Electrodynamics
Abrikosov also made significant contributions to quantum electrodynamics (QED), the quantum field theory of the electromagnetic force. His work in this area included the development of methods for calculating the properties of quantum fields and particles. He collaborated with other prominent physicists, such as Lev Gor'kov and Igor Dzyaloshinskii, to develop the Abrikosov-Gor'kov theory, which describes the behavior of superconductors with magnetic impurities.
Condensed Matter Physics
In addition to his work on superconductivity and QED, Abrikosov made substantial contributions to condensed matter physics. He studied the electronic properties of metals and semiconductors, focusing on phenomena such as electron-phonon interactions and magnetoresistance. His research in this field helped to advance the understanding of the fundamental properties of materials and their potential technological applications.
Professional Career
Early Career
After completing his Ph.D., Abrikosov joined the Institute for Physical Problems in Moscow, where he worked under the guidance of Lev Landau. During this time, he conducted research on various topics in theoretical physics, including superconductivity and quantum field theory. In 1965, he became a professor at the Moscow Institute of Physics and Technology, where he continued to teach and conduct research.
Later Career
In 1991, Abrikosov moved to the United States, where he joined the faculty of the University of Illinois at Urbana-Champaign. He continued his research on superconductivity and condensed matter physics, collaborating with other leading scientists in the field. In 2000, he was awarded the Nobel Prize in Physics, along with Vitaly Ginzburg and Anthony Leggett, for his pioneering work on superconductivity.
