[PAR] [TLE] Alexei Alexeyevich Abrikosov [SEP] Alexei Alexeyevich Abrikosov (Russian: Алексе́й Алексе́евич Абрико́сов ; 25 June 1928 – 29 March 2017) was a Soviet, Russian and American theoretical physicist whose main contributions are in the field of condensed matter physics.  He was awarded the Nobel Prize in Physics in 2003. [PAR] [TLE] Fermi liquid theory [SEP] Fermi liquid theory (also known as Landau–Fermi liquid theory) is a theoretical model of interacting fermions that describes the normal state of most metals at sufficiently low temperatures.  The interaction between the particles of the many-body system does not need to be small.  The phenomenological theory of Fermi liquids was introduced by the Soviet physicist Lev Davidovich Landau in 1956, and later developed by Alexei Abrikosov and Isaak Khalatnikov using diagrammatic perturbation theory.  The theory explains why some of the properties of an interacting fermion system are very similar to those of the Fermi gas (i.e. non-interacting fermions), and why other properties differ.
