from Wikipedia, the free encyclopedia

Dmitri Eduardovich Kharzeev (spelling according to the English transcription ; Russian Дмитрий Эдуардович Харзе́ев Dmitri Eduardowitsch Charséjew , born September 6, 1963 ) is a Russian theoretical physicist working in the USA.

Kharzeev studied at Lomonosov University , where he received his doctorate in 1990 and was a member of the Institute of Nuclear Physics from 1990 to 1993. As a post-doctoral student he was in the theory department of CERN (1994 to 1997), the Italian National Institute for Nuclear Physics INFN (and visiting professor at the University of Pavia 1992/93) and at the University of Bielefeld (with Helmut Satz , 1997). In 1997 he became a Fellow of the RIKEN-BNL Center at Brookhaven National Laboratory (BNL), which Tsung-Dao Lee directed. He stayed at the BNL, received tenure in 2000 and became head of the theory group in nuclear physics in 2004 and of the RIKEN-BNL theory group since 2015. In 2010 he became a professor at the State University of New York at Stony Brook , where he founded the Center for Quantum Materials in 2013, of which he is director.

Since 2007 he has also been an adjunct professor at Yale University . In 2014 he was visiting professor at the Autonomous University of Madrid.

He deals with nuclear physics, quantum chromodynamics (QCD) and solid state physics. He is known for the application of the chiral magnetic effect (CME) in nuclear and solid state physics. The effect describes the charge separation along an external magnetic field in systems with chiral imbalance (presence of chiral fermions). It is a macroscopic quantum effect, of a topological nature with regard to the gauge fields and a consequence of the chiral anomaly. In 2014 he and his colleagues detected this in the Dirac semimetal ZrTe5 (zirconium pentatelluride). In order to observe the CME in solids, quasiparticles in the form of almost massless fermions must be present (what the prefix Dirac stands for in Dirac semimetals) and they must be freely movable in three spatial dimensions, which is the case with zirconium pentatelluride, although there is also one has a layer-like structure like graphite. If an external magnetic field is switched on and an electric field is connected in parallel, the spins of the quasiparticles (which can be positively or negatively charged according to electrons and holes) orientate themselves to the magnetic field and you have a chiral separation of the charged quasiparticles: they move in the direction of the magnetic field, In the direction of which their spin is also oriented, one has right-handed particles (if the electric field is reversed with respect to the magnetic field, it becomes left-handed particles). He sees the potential of a loss-free current in the CME similar to that of superconductivity, and also applications in quantum computers (since chirality ensures stability and the two chiral states can encode information).

In nuclear physics, he deals with QCD matter and its phases in heavy ion collisions, such as those undertaken at RHIC in Brookhaven. Here, too, he examined the consequences of the CME, which enables the direct observation of topological effects of the QCD. Kharzeev is one of the authors of the KLN model (Kharzeev-Levin-Nardi) for many-particle scattering in nuclear collisions at high energies. He also deals with the application of the chiral anomaly in quantum information theory, quantum optics and graphs , in which he sees an analogy to quarks in quark-gluon plasmas (the quasiparticle excitations resemble massless Diracfermions, instead of QCD there is a strong Coulomb interaction). He holds a patent on Graphene Magnet Multilayers (GMM), which he sees as a possible basis for processors and memories in spintronics.

In 2006 he became a Fellow of the American Physical Society and in 2010 of the American Association for the Advancement of Science . In 2013 he received a Humboldt Research Award . In 2005 he was a Sackler Fellow and Emilio Segré Distinguished Scholar. In 1986 he won the Soviet national competition for physics students.
