Lattice QCD and dense quark matter
M. P. Lombardo, K. Splittorff, J. J. M. Verbaarschot
This talk summarizes recent progress in lattice QCD for dense quark matter. The emphasis is on the insights obtained from analytical results derived within chiral perturbation theo…
Fluctuations, correlations and the sign problem in QCD
M. P. Lombardo, K. Splittorff, J. J. M. Verbaarschot
We study the distribution of the phase angle and the magnitude of the fermion determinant as well as its correlation with the chiral condensate and the baryon number for QCD at non…
The Fluctuations of the Quark Number and of the Chiral Condensate
M. P. Lombardo, K. Splittorff, J. J. M. Verbaarschot
The distributions of the quark number and chiral condensate over the gauge fields are computed for QCD in Euclidean space at nonzero quark chemical potential. As both operators are…
The sign problem across the QCD phase transition
Jens O. Andersen, Lars T. Kyllingstad, Kim Splittorff
The average phase factor of the QCD fermion determinant signals the strength of the QCD sign problem. We compute the average phase factor as a function of temperature and baryon ch…
Distributions of the Phase Angle of the Fermion Determinant in QCD
M. P. Lombardo, K. Splittorff, J. J. M. Verbaarschot
The distribution of the phase angle and the magnitude of the fermion determinant as well as its correlations with the baryon number and the chiral condensate are studied for QCD at…
