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…
Handbook Article on Applications of Random Matrix Theory to QCD
J. J. M. Verbaarschot
In this chapter of the Oxford Handbook of Random Matrix Theory we introduce chiral Random Matrix Theories with the global symmetries of QCD. In the microscopic domain, these theori…
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…
Topology and chiral random matrix theory at nonzero imaginary chemical potential
C. Lehner, M. Ohtani, J. J. M. Verbaarschot +1
We study the effect of topology for a random matrix model of QCD at nonzero imaginary chemical potential or nonzero temperature. Non-universal fluctuations of Dirac eigenvalues lea…
Induced Violation of Time-Reversal Invariance in the Regime of Weakly Overlapping Resonances
B. Dietz, T. Friedrich, H. L. Harney +5
We measure the complex scattering amplitudes of a flat microwave cavity (a "chaotic billiard"). Time-reversal T-invariance is partially broken by a magnetized ferrite placed within…
