The sign problem in the -regime of QCD
K. Splittorff
QCD in the -regime at nonzero baryon chemical potential is reviewed. The focus is on aspects of the sign problem which are relevant for lattice QCD. It is discussed how spon…
Phase of the Fermion Determinant at Nonzero Chemical Potential
K. Splittorff, J. J. M. Verbaarschot
We show that in the microscopic domain of QCD (also known as the -domain) at nonzero chemical potential the average phase factor of the fermion determinant is nonzero for $μ< m_…
A new Chiral Two-Matrix Theory for Dirac Spectra with Imaginary Chemical Potential
G. Akemann, P. H. Damgaard, J. C. Osborn +1
We solve a new chiral Random Two-Matrix Theory by means of biorthogonal polynomials for any matrix size . By deriving the relevant kernels we find explicit formulas for all $(n,…
Surprises for QCD at Nonzero Chemical Potential
K. Splittorff, J. J. M. Verbaarschot
In this lecture we compare different QCD-like partition functions with bosonic quarks and fermionic quarks at nonzero chemical potential. Although it is not a surprise that the gro…
QCD with Bosonic Quarks at Nonzero Chemical Potential
K. Splittorff, J. J. M. Verbaarschot
We formulate the low energy limit of QCD like partition functions with bosonic quarks at nonzero chemical potential. The partition functions are evaluated in the parameter domain t…
Microscopic eigenvalue correlations in QCD with imaginary isospin chemical potential
P. H. Damgaard, U. M. Heller, K. Splittorff +2
We consider the chiral limit of QCD subjected to an imaginary isospin chemical potential. In the epsilon-regime of the theory we can perform precise analytical calculations based o…
