Future Requirements of Lattice Field Theory Calculations on European High-Performance Computing Facilities
Gert Aarts, Gunnar Bali, Jacob Finkenrath +4
Lattice field theory provides a first-principles framework for studying properties of strongly interacting quantum field theories in elementary particle physics. Researchers in lat…
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…
Heavy quark thermodynamics with anisotropic lattices
Jon-Ivar Skullerud, Rachel Horohan D'Arcy, Gert Aarts +11
We present recent results from the FASTSUM collaboration, using anisotropic lattice QCD to study spectral properties of heavy quarkonia and open heavy flavour systems at high tempe…
On the effective restoration of symmetry at finite temperature
Gert Aarts, Chris Allton, Ryan Bignell +4
The symmetry of the massless QCD Lagrangian is explicitly broken by the axial anomaly, but it may be effectively restored at finite temperature. Determining the temperatur…
symmetry restoration at finite temperature with mesonic correlators
Ryan Bignell, Gert Aarts, Chris Allton +4
The symmetry of the massless QCD Lagrangian is explicitly broken in the quantised theory by the anomaly. It may be effectively restored at some finite temperature, which w…
The curvature of the pseudo-critical line in the QCD phase diagram from mesonic lattice correlation functions
Antonio Smecca, Gert Aarts, Chris Allton +6
In the QCD phase diagram, the dependence of the pseudo-critical temperature, , on the baryon chemical potential, , is of fundamental interest. The variation of $…
