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,…
Extracting from small lattices: unquenched results
P. H. Damgaard, U. M. Heller, K. Splittorff +2
We calculate the response of the microscopic Dirac spectrum to an imaginary isospin chemical potential for QCD with two dynamical flavors in the chiral limit. This extends our prev…
On Generalized Gauge-Fixing in the Field-Antifield Formalism
I. A. Batalin, K. Bering, P. H. Damgaard
We consider the problem of covariant gauge-fixing in the most general setting of the field-antifield formalism, where the action W and the gauge-fixing part X enter symmetrically a…
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…
Distributions of Dirac Operator Eigenvalues
G. Akemann, P. H. Damgaard
The distribution of individual Dirac eigenvalues is derived by relating them to the density and higher eigenvalue correlation functions. The relations are general and hold for any…
Vector and Axial-Vector Propagators in the ε-Regime of QCD
P. H. Damgaard, P. Hernandez, K. Jansen +2
Using quenched and unquenched chiral perturbation theory we compute vector and axial current two-point functions at finite volume and fixed gauge field topology, in the so-called ε…
