Lattice field theories with a sign problem
Gert Aarts, Dénes Sexty
The sign problem obstructs the determination of the QCD phase diagram in the temperature-baryon chemical potential plane using lattice QCD. We review the sign problem in QCD and re…

Finite-density equation of state of hot QCD using the complex Langevin equation
Michael Mandl, Dénes Sexty, Daniel Unterhuber
We present the results of continuum-extrapolated lattice simulations of quantum chromodynamics (QCD) above the crossover temperature and for unprecedentedly high baryon densities a…
