Systematic approximation for QCD at non-zero density
Gert Aarts, Benjamin Jäger, Erhard Seiler +2
We use the heavy dense formulation of QCD (HD-QCD) as the basis for an analytic expansion as systematic approximation to QCD at non-zero density, keeping the full Yang-Mills action…
QCD at nonzero chemical potential: recent progress on the lattice
Gert Aarts, Felipe Attanasio, Benjamin Jäger +3
We summarise recent progress in simulating QCD at nonzero baryon density using complex Langevin dynamics. After a brief outline of the main idea, we discuss gauge cooling as a mean…
New algorithms for finite density QCD
Denes Sexty
Recent progress of the complex Langevin method and the Lefschetz thimble in connection with the sign problem is reviewed. These methods rely on the complexification of the original…
Exploring the phase diagram of QCD with complex Langevin simulations
Gert Aarts, Felipe Attanasio, Benjamin Jäger +3
Simulations of QCD with a finite chemical potential typically lead to a severe sign problem, prohibiting any standard Monte Carlo approach. Complex Langevin simulations provide an…
Complex Langevin dynamics for SU(3) gauge theory in the presence of a theta term
Lorenzo Bongiovanni, Gert Aarts, Erhard Seiler +1
One of the yet unsolved questions of QCD in the context of the Standard Model is to explain the strong CP problem. A way to look for a better understanding of it is to investigate…
Progress in complex Langevin simulations of full QCD at nonzero density
Denes Sexty
Progress in the application of the complex Langevin method to full QCD at non-zero chemical potential is reported. The method evades the sign problem which makes naive simulations…
