Suppression of Baryon Diffusion and Transport in a Baryon Rich Strongly Coupled Quark-Gluon Plasma.
Five dimensional black hole solutions that describe the QCD crossover transition seen in (2+1)-flavor lattice QCD calculations at zero and nonzero baryon densities are used to obtain predictions for the baryon susceptibility, baryon conductivity, baryon diffusion constant, and thermal conductivity of the strongly coupled quark-gluon plasma in the range of temperatures 130 MeV≤T≤300 MeV and ba...
متن کاملQCD at Non-Zero Density : Lattice Results
A concise review of the progress of lattice calculations at non-zero density since QM2006, with emphasis on the high baryon density, low temperature domain. Possibilities for exploring densities higher than those studied by standard techniques are analysed. The phase transitions of cold, dense matter, where the sign problem remains severe, are discussed in the context of QCD-like models and app...

We discuss the quenched limit of lattice QCD at non-zero baryon number density. We find evidence for a mixed phase that becomes broader with increasing baryon number. Although the action is explicitly Z(3) symmetric the Polyakov loop expectation value becomes non-zero already in the low temperature phase. It indicates that the heavy quark potential stays finite at large distances, i.e. the stri...
متن کاملThe quenched limit of lattice QCD at non - zero baryon number
We discuss the thermodynamics of gluons in the background of static quark sources. In order to do so we formulate the quenched limit of QCD at non-zero baryon number. A first numerical analysis of this system shows that it undergoes a smooth deconfining transition. We find evidence for a region of coexisting phases that becomes broader with increasing baryon number density. Although the action ...
متن کاملVector condensation in QCD
The properties of the QCD vacuum at quark chemical potentials on the order of the pion mass and at zero temperature are by now quite well understood. The insight into this non-perturbative regime of QCD is obtained using chiral perturbation theory at nonzero quark chemical potentials [1–8]. The results apply not only to ordinary QCD but also to two color QCD and to QCD with quarks in the adjoin...
