The phase boundary for the chiral transition in (2+1)-flavor QCD at small values of the chemical potential
the chiral transition (2+1)-flavor QCD
2011/1/6
We determine the chiral phase transition line in (2+1)-flavor QCD for small values of the light quark chemical potential. We show that for small values of the chemical potential the curvature of the p...

Proof of universality of electrical conductivity at finite chemical potential
electrical conductivity finite chemical potential
2010/12/23
It was proposed in arXiv:1008.2944 that, for certain gauge theories with gravity duals, electrical conductivity at finite chemical potential is universal. Here we provide a general proof that, when m...

Extracting scattering parameters isospin chemical potential
2011/1/6
Hadronic scattering mediated through the strong interaction has been an area of great interest for both theory and experiment. Recently, lattice QCD calculations of scattering processes from first pri...

Symmetry Breaking Phase Transitions in ABJM Theory with a Finite U(1) Chemical Potential
ABJM Theory Finite U(1) Chemical Potential
2010/12/24
We consider the U(1) charged sector of ABJM theory at finite temperature, which corresponds to the Reissner-Nordstrom AdS black hole in the dual type IIA supergravity description. Including back-react...
Absence of sign problem in the (saddle point approximation of the) nilpotency expansion of QCD at finite chemical potential
nilpotency expansion QCD finite chemical potential
2011/1/6
We have developed a method to derive the (approximate) quark contribution to the fermion free energy of QCD on a lattice, at finite temperature and chemical potential, with Kogut-Susskind fermions in ...
Constraints for the QCD phase diagram from imaginary chemical potential
the QCD phase diagram imaginary chemical potential
2011/1/6
We present unambiguous evidence from lattice simulations of N_f=3 QCD for two tricritical points in the (T,m) phase diagram at fixed imaginary \mu/T=i\pi/3 mod. 2\pi/3, one in the light and one in the...
We discuss the distribution of the quark number over the gauge fields for QCD at nonzero quark chemical potential. As the quark number operator is non-hermitian, the distribution is over the complex p...
