Supercomputing the Matter at Extremes: From Hadrons to Quarks

prof. Peter Petreczky


At very high temperatures the strongly interacting matter is expected to undergo a transition to a new state, where the dominant degrees of freedom are quarks and gluons instead of hadrons.

I will discuss this transition and the properties of the new form matter based on large scale numerical calculations within lattice regularized Quantum Chromodynamics (LQCD). In particular, I will discuss equation of state, Debye screening and fluctuations of conserved charges.  I will show how the fluctuations of conserved charges can be used to understand the transition from hadrons to quarks. I will also compare the numerical LQCD results with pictcure based on weakly interacting gas of quarks and gluons.
