QCD thermodynamics with nonzero chemical potential at $N_t=6$ and effects from heavy quarks

Understand

We extend our work on QCD thermodynamics with 2+1 quark flavors at nonzero chemical potential to finer lattices with $N_t=6$.

• We study the equation of state and other thermodynamic quantities, such as quark number densities and susceptibilities, and compare them with our previous results at $N_t=4$.
• We also calculate the effects of the addition of the charm and bottom quarks on the equation of state at zero and nonzero chemical potential.
• These effects are important for cosmological studies of the early Universe.
