Description

The equation of state of hadronic matter is of high importance for
many fields, ranging from heavy-ion collisions to neutron stars. Non-
perturbative methods to simulate QCD encounter difficulties at finite
chemical potential 𝜇 due to the so-called sign problem. We employ the
complex Langevin method to circumvent this problem and carry out
simulations at a variety of values for temperature and 𝜇. We present
results on the pressure, energy and entropy equations of state, as well
as a numerical observation of the Silver Blaze phenomenon.
