Lattice QCD at finite isospin chemical potential and temperature
We simulate lattice QCD at a finite chemical potential μI for isospin (I3) at zero and finite temperatures. At some μI = μc QCD has a second order transition with mean-field critical exponents to a state where (I3) is broken spontaneously by a charged pion condensate. Heating the system with μI > μc we find there is some temperature at which this condensate evaporates. This transition appears t...
متن کاملThermal Pions and Isospin Chemical Potential Effects
The density corrections, in terms of the isospin chemical potential μI , to the mass of the pions are investigated in the framework of the SU(2) low energy effective chiral invariant lagrangian. As a function of temperature and μI = 0, the mass remains quite stable, starting to grow for very high values of T , confirming previous results. However, the dependence for a non-vanishing chemical pot...
متن کاملTwo-flavor QCD phases and condensates at finite isospin chemical potential
We study the phase structure and condensates of two-flavor QCD at finite isospin chemical potential in the framework of a confining, Dyson-Schwinger equation model. We find that the pion superfluidity phase is favored at high enough isospin chemical potential. A new gauge invariant mixed quark-gluon condensate induced by isospin chemical potential is proposed based on Operator Product Expansion...
متن کاملPartially quenched QCD with a chemical potential
Using a chiral random matrix theory we can now derive the low energy partition functions and Dirac eigenvalue correlations of QCD with different chemical potentials for the dynamical and valence quarks. The results can also be extended to complex (and purely imaginary) chemical potential. We also discuss possible applications such as fitting to low energy constants and understanding the phase d...
متن کاملHolographic dual of a boost-invariant plasma with chemical potential
We construct a gravity dual of a boost-invariant flow of an N = 4 SU(N) supersymmetric Yang-Mills gauge theory plasma with chemical potential. We present both a firstorder corrected late-time solution in Eddington-Finkelstein coordinates and a zeroth-order solution in parametric form in Fefferman-Graham coordinates. The resulting background takes the form of a time-dependent AdS Reissner-Nordst...
