Microscopic Spectrum of the Wilson Dirac Operator
P. H. Damgaard, K. Splittorff, J. J. M. Verbaarschot
We calculate the leading contribution to the spectral density of the Wilson Dirac operator using chiral perturbation theory where volume and lattice spacing corrections are given b…
Chiral Condensate at Nonzero Chemical Potential in the Microscopic Limit of QCD
J. C. Osborn, K. Splittorff, J. J. M. Verbaarschot
The chiral condensate in QCD at zero temperature does not depend on the quark chemical potential (up to one third the nucleon mass), whereas the spectral density of the Dirac opera…
Nonhermitian Supersymmetric Partition Functions: the case of one bosonic flavor
K. Splittorff, J. J. M. Verbaarschot, M. R. Zirnbauer
We discuss the supersymmetric formulation of the nonhermitian random matrix partition function with one bosonic flavor. This partition function is regularized by adding one…
Triage of the Sign Problem
K. Splittorff, J. J. M. Verbaarschot
We discuss the sign problem in QCD at nonzero chemical potential and its relation with chiral symmetry breaking and the spectrum of the Dirac operator using the framework of chiral…
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,…
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…
