Fluctuations of Goldstone modes and the chiral transition in QCD
Frithjof Karsch
We provide evidence for the influence of thermal fluctuations of Goldstone modes on the chiral condensate at finite temperature. We show that at fixed temperature, T<Tc, in the vic…
Calculating Quark Number Susceptibilities with Domain-Wall Fermions
Prasad Hegde, Frithjof Karsch, Christian Schmidt
We present results from calculations of different quark number and hadronic susceptibilities on 2+1-flavor dynamical domain wall ensembles. We find that the iso-spin and electric c…
The Spatial String Tension and Dimensional Reduction in QCD
M. Cheng, S. Datta, J. van der Heide +12
We calculate the spatial string tension in (2+1) flavor QCD with physical strange quark mass and almost physical light quark masses using lattices with temporal extent N_tau=4,6 an…
Equation of state and more from lattice regularized QCD
Frithjof Karsch
We present results from a calculation of the QCD equation of state with two light (up, down) and one heavier (strange) quark mass performed on lattices with three different values…
Lattice cut-off effects and their reduction in studies of QCD thermodynamics at non-zero temperature and chemical potential
P. Hegde, F. Karsch, E. Laermann +1
We clarify the relation between the improvement of dispersion relations in the fermion sector of lattice regularized QCD and the improvement of bulk thermodynamic observables. We s…
