报告摘要：

  Under conditions of extremely high temperature or large densities the constituents of hadrons, quarks and gluons, can get liberated and form a new, largely unexplored state of matter——quark gluon plasma, which is supposed to be the state of the early universe a few microseconds after the big bang. First-principle numerical calculations based on lattice regularized Quantum Chromodynamics (Lattice QCD) allow us to study the transition from the hadronic phase to the quark gluon plasma phase. They provide invaluable inputs to the interpretation of large experimental heavy-ion programs at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory, New York and the Large Hadron Collider (LHC) at CERN, Switzerland. In the talk I will start by a general introduction to heavy ion collision physics and Lattice QCD, and then review recent success at understanding the properties of hot and dense matter from lattice QCD as well as the role of supercomputers in our research.
