The equation of state with non-equilibrium methods


  • Mr. Alessandro NADA

Primary authors


Jarzynski's equality provides an elegant and powerful tool to compute directly differences in free-energy in Monte Carlo simulations and it can be readily extended to lattice gauge theories to compute a large set of physically interesting observables. In this talk we present a novel technique to determine the thermodynamics of strongly-interacting matter based on this relation, which allows for a direct and efficient determination of the pressure using out-of-equilibrium Monte Carlo simulations on the lattice. We present results for the equation of state of the SU(3) Yang-Mills theory in the confined and deconfined phases. Finally, we discuss the generalization of this method for theories with fermions, with particular focus on the equation of state of QCD.
