Chaos and stability in a two-parameter family of convex billiard tables
Péter Bálint, Miklós Halász, Jorge Hernández-Tahuilán +1
We study, by numerical simulations and semi-rigorous arguments, a two-parameter family of convex, two-dimensional billiard tables, generalizing the one-parameter class of oval bill…
An improved random matrix model for the chiral phase transition in QCD at finite chemical potential
M. A. Halasz
We consider a lattice-inspired random matrix model for the QCD chiral phase transition at finite chemical potential. Useful features of the usual RMM for QCD at finite chemical pot…
Skyrmion-anti-Skyrmion Annihilation with Omega Mesons
M. A. Halasz, R. D. Amado
We study numerically the annihilation of an omega-stabilized Skyrmion and an anti-Skyrmion in three spatial dimensions. To our knowledge this is a first successful simulation of Sk…
Two Skyrmion Dynamics with Omega Mesons
R. D. Amado, M. A. Halasz, P. Protopapas
We present our first results of numerical simulations of two skyrmion dynamics using an -meson stabilized effective Lagrangian. We consider skyrmion-skyrmion scattering with a f…
Random Matrices and the Convergence of Partition Function Zeros in Finite Density QCD
M. A. Halasz, J. C. Osborn, M. A. Stephanov +1
We apply the Glasgow method for lattice QCD at finite chemical potential to a schematic random matrix model (RMM). In this method the zeros of the partition function are obtained b…
Random Matrices and the Glasgow Method
Miklos-Adam Halasz
A simple non-Hermitean random matrix (RM) model is used to study the Glasgow method of finite-density lattice QCD. The zeros of the RM partition function are evaluated through an a…
Photon Rates for Heavy-Ion Collisions from Hidden Local Symmetry
M. A. Halasz, J. V. Steele, G. Q. Li +1
We study photon production from the hidden local symmetry approach that includes pions, rho and a1 mesons and compute the corresponding photon emission rates from a hadronic gas in…
Random matrix triality at nonzero chemical potential
M. A. Halasz, J. C. Osborn, J. J. M. Verbaarschot
We introduce three universality classes of chiral random matrix ensembles with a nonzero chemical potential and real, complex or quaternion real matrix elements. In the thermodynam…
Fermion determinants in matrix models of QCD at nonzero chemical potential
M. A. Halasz, A. D. Jackson, J. J. M. Verbaarschot
The presence of a chemical potential completely changes the analytical structure of the QCD partition function. In particular, the eigenvalues of the Dirac operator are distributed…
Yang-Lee zeros of a random matrix model for QCD at finite density
M. A. Halasz, A. D. Jackson, J. J. M. Verbaarschot
We study the Yang-Lee zeros of a random matrix partition function with the global symmetries of the QCD partition function. We consider both zeros in the complex chemical potential…
Universal correlations in spectra of the lattice QCD Dirac operator
M. A. Halasz, T. Kalkreuter, J. J. M. Verbaarschot
Recently, Kalkreuter obtained complete Dirac spectra for lattice gauge theory both for staggered fermions and for Wilson fermions. The lattice size was as large as .…
Effective Lagrangians and Chiral Random Matrix Theory
M. A. Halasz, J. J. M. Verbaarschot
Recently, sum rules were derived for the inverse eigenvalues of the Dirac operator. They were obtained in two different ways: i) starting from the low-energy effective Lagrangian a…
Universal fluctuations in spectra of the lattice Dirac operator
M. A. Halasz, J. J. M. Verbaarschot
Recently, Kalkreuter obtained the complete Dirac spectrum for an lattice gauge theory with dynamical staggered fermions on a lattice for and . We perf…
