Phase quenched QCD (A09*)

• Subject Area: Nuclear and Elementary Particle Physics, Quantum Mechanics, Relativity, Fields
• Term: since 2026
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 315477589

This project will carry out lattice simulations of phase quenched QCD in order to provide strict bounds for the QCD equation of state and other QCD observables at non-zero baryon chemical potentials. In particular, we will compute a constraint on the QCD pressure at low temperatures and large chemical potentials, which can be utilized in the agnostic modeling of the neutron star equation of state and at large densities to make contact with perturbation theory. We will also find similar constraints in the vicinity and above the chiral crossover to improve Taylor expansions employed to explore the QCD phase diagram.
