Equation of state from complex Langevin simulations

Abstract

We use complex Langevin simulations to study the QCD phase diagram with two light quark flavours. In this study, we use Wilson fermions with an intermediate pion mass of $\sim 480$MeV. By studying thermodynamic quantities, in particular at lower temperatures, we are able to describe the equation of state.
