Phase Diagram of the Dirac Spectrum at Nonzero Chemical Potential
J. C. Osborn, K. Splittorff, J. J. M. Verbaarschot
The Dirac spectrum of QCD with dynamical fermions at nonzero chemical potential is characterized by three regions, a region with a constant eigenvalue density, a region where the e…
Is the chiral phase transition induced by a metal-insulator transition?
Antonio M. Garcia-Garcia, James C. Osborn
We investigate the QCD Dirac operator with gauge configurations given by a liquid of instantons in the region of temperatures about the chiral phase transition. Both the quenched a…
Adaptive Multigrid Algorithm for the QCD Dirac-Wilson Operator
J. Brannick, R. C. Brower, M. A. Clark +2
We present a new multigrid solver that is suitable for the Dirac operator in the presence of disordered gauge fields. The key behind the success of the algorithm is an adaptive pro…
