Miklos Gyulassy

from Wikipedia, the free encyclopedia

Miklos Gyulassy (born March 9, 1949 in Szolnok ) is a Hungarian - American nuclear physicist . He is known for his contributions to relativistic heavy ion physics ( quark-gluon plasma , hot nuclear matter and its phases).

Life

Gyulassy studied at the University of California, Berkeley with a bachelor's degree in 1970 and a doctorate in physics in 1974 with Eyvind Wichmann . As a post-doctoral student he was with the Society for Heavy Ion Research in Darmstadt and with Walter Greiner in Frankfurt until 1976 and at the Lawrence Berkeley National Laboratory (LBNL) from 1976 , and from 1981 as Senior Staff Scientist. From 1993 he was a professor at Columbia University . In 2015 he became Professor Emeritus at Columbia University and connected with the LBNL and Central China Normal University (CCNU) in Wuhan .

As a post-doctoral student at Greiner, he dealt with vacuum polarization in strong Coulomb fields , which was also a topic of his dissertation (correction of the energy levels in muonic atoms due to vacuum polarization in strong fields). At LBNL he explored Pion - interferometry (using optical Intensitätsinterferometrie on pions) Charmonium decay, QCD -Transporttheorie, stop by baryons in nuclear matter and collective hydrodynamic flows of QCD matter in heavy-ion collisions.

In 2003 he announced the discovery of quark-gluon plasma at the Relativistic Heavy Ion Collider (RHIC) in Brookhaven. In 2004, together with Larry McLerran , he proposed an interpretation of the first three years of data collection for heavy ion collisions at the RHIC with references to the discovery of two new phases of QCD matter: strongly interacting quark-gluon plasma (sQGP) and color-glass condensate ( Color Glass Condensate , CGC). In particular, the observed collective flow behavior of the QCD matter after the collision, corresponding to an almost ideal liquid and elliptical flow, was an indication of the formation of a quark-gluon plasma in the RHIC experiments.

In 1991 he and Xin-Nian Wang developed the HIJING model ( Heavy Ion Jet Interaction Generator ), a Monte Carlo simulator for predicting exclusive processes in high-energy proton-proton, proton-nucleus and nucleus-nucleus collisions, and said strong nuclear Correlations in jets with high transverse impulses, which were observed at RHIC in 2001.

With Peter Levai and Ivan Vitev he developed the GLV model, further developed to DGLV with Magdalena Djordjevic, for the description of energy losses from jets in QCD matter ( jet quenching ). The type of energy loss (mainly induced gluon emission instead of collisions in quark-gluon plasma) provides information about and gives clues to the quark-gluon plasma, which leads to a strong suppression of jets. Gyulassy is further developing such tomographic models of energy losses from jets in QCD matter based on perturbation theory QCD with colleagues (CUJET 2.0). Indications of jet quenching were found at RHIC. With even higher energy than at RHIC, the forecasts will also be checked from 2010 at ALICE at the Large Hadron Collider (LHC) of CERN , where the first direct observation of jet quenching was reported in 2010.

Since 2007 he has also been working on checking predictions of AdS-CFT correspondence for heavy ion collisions. Since 2015 he has been working with Jinfeng Liao and students on the theory of jet quenching in semi-quark-gluon-monopole plasmas (sQGMP) with CUJET3.0, the high-energy heavy ion collisions are generated at the RHIC and the LHC.This theory also takes into account non-perturbation-theoretical QCD contributions (chromomagnetic monopoles).

Awards and memberships

For 2015 he received the Tom W. Bonner Prize for Nuclear Physics . In 1987 he received the Ernest Orlando Lawrence Prize and in 1986 the Humboldt Research Prize . He is a Fellow of the American Physical Society and a foreign member of the Hungarian Academy of Sciences. 1983 to 1996 he was on the planning committee for nuclear physics of the Department of Energy (DOE).
