Description
We study lattice QCD in the limit of infinite gauge coupling on a discrete spatial yet continuous Euclidean time lattice at finite baryon chemical potential $\mu_B$. The continuous time framework is based on sending $N_\tau\rightarrow \infty$ and the bare anisotropy to infinity while fixing the temperature in a non-perturbative setup. This leads to a sign problem free algorithm that allows us to study the whole $\mu_B$-$T$ plane. We measure the pressure and energy density at finite temperature and baryon density in the chiral limit. We compare with Taylor coefficients from the measurement of baryon fluctuations. Calculations are based on our worm type Monte Carlo algorithm featuring a polymer resummation scheme that improves accuracy.
