                  Localized quarks in the quark-gluon plasma

Kivonatos ismertetés:
At high temperature strongly interacting matter undergoes dramatic changes because quarks that are normally confined in 
hadrons get deconfined and melt into a quark-gluon plasma. Lattice QCD simulations allow us to look at the details of how 
this transition occurs. A particularly interesting and recently explored phenomenon is that at the transition the lowest 
quark eigenstates of the Dirac operator become spatially localized. In the talk I will demonstrate how to detect this 
localization transition in lattice simulations and also discuss its close connection to similar Anderson-type transitions 
occurring in condensed matter systems. Finally, I will speculate on how quark localization might be related to deconfinement 
and chiral symmetry restoration in the quark-gluon plasma.
