Holographic Model at Finite Temperature with R-charge density
We consider a holographic model of QCD at finite temperature with nonzero chemical potentials conjugate to R-charge densities. A critical surface of the confinement-deconfinement phase transition is shown for five-dimensional charged black hole solution given by Behrnd, Cvetič and Sabra. On a special section of the parameter space, we find an critical curve being similar to the one expected in ...
متن کاملCritical point in finite density lattice QCD by canonical approach
We propose a method to find the QCD critical point at finite density calculating the canonical partition function ZC(T, N) by Monte-Carlo simulations of lattice QCD, and analyze data obtained by a simulation with two-flavor p4-improved staggered quarks with pion mass mπ ≈ 770MeV. It is found that the shape of an effective potential changes gradually as the temperature decreases and a first orde...
متن کاملRelaxation of quantum dots in a magnetic field at finite bias -- charge, spin and heat currents
We perform a detailed study of the effect of finite bias and magnetic field on the tunneling-induced decay of the state of a quantum dot by applying a recently discovered general duality [PRB 93, 81411 (2016)]. This duality provides deep physical insight into the decay dynamics of electronic open quantum systems with strong Coulomb interaction. It associates the amplitudes of decay eigenmodes o...
متن کاملModel at Finite Chemical Potential in a Constant Magnetic Field
We investigate the influence of an external magnetic field on chiral symmetry breaking in the Nambu-Jona-Lasinio (NJL) model at finite temperature and chemical potential. According to the Fock-Schwinger proper-time method, we calculate the effective potential in the leading order of the 1/Nc expansion. The phase boundary dividing the symmetric phase and the broken phase is illustrated numerical...
متن کاملQcd at Finite Density
At sufficiently high temperature and density, quantum chromodynamics (QCD) predicts phase transition from the hadronic phase to the quark-gluon plasma phase. Lattice QCD is the most useful tool to investigate this critical phenomenon, which status is briefly reviewed. The usual problem in the Lagrangian formulation at finite density is either an incorrect continuum limit or its complex action a...
