Pressure and speed of sound in two-flavor color-superconducting quark matter at next-to-leading order
We calculate the next-to-leading order corrections to the pertubative QCD pressure arising from the color superconducting gap at large net baryon density. We find a quite sizeable correction!

Constraining the equation of state in neutron-star cores via the long-ringdown signal
We show that the behavior of the gravitational wave emission in the post-merger phase of a binary neutron-star merger should show a tight correlation with the pressure and density reached in the cores of maximally massive neutron stars.

Estimate for the Bulk Viscosity of Strongly Coupled Quark Matter Using Perturbative QCD and Holography
We calculate state-of-the-art results for an important transport property in deconfined quark matter: the bulk viscosity.

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.
