Operator relations and chemical effects on chiral dynamics in QCD
We discuss effects of chemical potential on the dynamics of chiral transition by the Taylor expansion method in lattice QCD. Operators and their Taylor expansions which characterise the chiral dynamics are related through Maxwell’s relations and Chiral Ward identities. This reduces the computation to just measuring the renormalized expectation values of the chiral condensate and its Taylor coef...

متن کاملThe density of states method at non - zero chemical potential
We study the QCD phase diagram by first principle lattice calculations at so far unreached high densities. For this purpose we employ the density of states method. Unimproved staggered fermions, which describe four quark flavors in the continuum are used in this analysis. Though the method is quite expensive, small lattices show an indication for a triple-point connecting three different phases...
متن کاملQcd at Non-zero Chemical Potential and Temperature from the Lattice
A study of QCD at non-zero chemical potential, μ, and temperature, T , is performed using the lattice technique. The transition temperature (between the confined and deconfined phases) is determined as a function of μ and is found to be in agreement with other work. In addition the variation of the pressure and energy density with μ is obtained for μ ∼ > 0. These results are of particular relev...
متن کاملQuark Fluctuations in a Chiral Model at finite chemical potential
During recent years the phenomenological importance of fluctuations in finite temperature/finite density QCD has been recognized [1]. The analysis of fluctuations is an essential method to characterize the thermodynamic properties of a system. Enhanced fluctuations signal the onset of a phase transition [2]. Thus, measuring modifications in the magnitude of fluctuations in heavy ion collisions ...
