The Sign Problem is the Solution
J. C. Osborn, K. Splittorff, J. J. M. Verbaarschot
The unquenched spectral density of the Dirac operator at is complex and has oscillations with a period inversely proportional to the volume and an amplitude that grows exp…
Chiral Symmetry Breaking at Nonzero Chemical Potential
J. C. Osborn, K. Splittorff, J. J. M. Verbaarschot
We consider chiral symmetry breaking at nonzero chemical potential and discuss the relation with the spectrum of the Dirac operator. We solve the so called Silver Blaze Problem tha…
A New Method for Determining on the Lattice
P. H. Damgaard, Urs M. Heller, K. Splittorff +1
We derive the two-point spectral correlation function of the Dirac operator with a specific external source in the -regime of QCD. This correlation function has a unique and str…
Lattice simulations of QCD with versus phase quenched QCD
K. Splittorff
Previously published lattice results for QCD at are compared to analytic predictions for phase quenched QCD. We observe that the strength of the sign problem in QCD is l…
Chiral Symmetry Breaking and the Dirac Spectrum at Nonzero Chemical Potential
J. C. Osborn, K. Splittorff, J. J. M. Verbaarschot
The relation between the spectral density of the QCD Dirac operator at nonzero baryon chemical potential and the chiral condensate is investigated. We use the analytical result for…
