Equation of state at neutron-star densities and beyond from perturbative QCD
We show that equations of state that are extremely stiff within the cores of maximally massive neutron stars are incompatible with the behavior of the speed of sound at high densities 25-40$n_\mathrm{sat}$

Bounding the QCD Equation of State with the Lattice
We show that the pressure of phase-quenched QCD -- a theory that is simpler to compute on the lattice -- agrees with the pressure of true QCD up to next-to-next-to-next to leading order, where it differes in only one part of one diagram (pictured).

Equation of State of Cold Quark Matter to $O(\alpha_s^3 \ln \alpha_s)$
We calculate the state-of-the-art pressure of cold and dense deconfined matter by accounting for the physics from all of the long-wavelength, dynamically screened gluons at next-to-next-to-next-to-leading order.
