Lowest eigenvalues of the Dirac operator for two color QCD at finite density

Elmar Bittner, Maria-Paola Lombardo, Harald Markum +1

We investigate the eigenvalue spectrum of the staggered Dirac matrix in full QCD with two colors and finite chemical potential. Along the strong-coupling axis up to the temperature…

Finite temperature field theory

M. -P. Lombardo

These lectures review phases and phase transitions of the Standard Model, with emphasis on those aspects which are amenable to a first principle study. Model calculations and theor…

Eigenvalues of the QCD Dirac operator at finite temperature and density

Elmar Bittner, Maria-Paola Lombardo, Harald Markum +1

We investigate the eigenvalue spectrum of the staggered Dirac matrix in two-color QCD at nonzero temperature and at baryon density when the eigenvalues become complex. The quasi-ze…

Universality and Chaos in Quantum Field Theories

B. A. Berg, E. Bittner, M. -P. Lombardo +3

We investigate the eigenvalue spectrum of the staggered Dirac matrix in SU(3) gauge theory and in full QCD as well as in quenched U(1) theory on various lattice sizes. As a measure…

Interquark potential, susceptibilities and particle density of two color QCD at finite chemical potential and temperature

M. -P. Lombardo

We explore the phase diagram of SU(2) Lattice Gauge Theory with dynamical fermions in the temperature, mass, chemical potential space. We observe qualitative changes of the depende…

Deconfinement and non-zero baryon density

M. -P. Lombardo

I discuss a few issues related with deconfinement at finite baryon density by considering lattice results for two colors QCD and ``toy'' studies of three colors QCD.
