Constraints for the QCD phase diagram from imaginary chemical potential
Constraints QCD phase diagram imaginary chemical potential
2011/1/13
We present unambiguous evidence from lattice simulations of Nf = 3 QCD for two tricritical
points in the (T,m) phase diagram at fixed imaginary m/T = ip /3 mod. 2p /3, one in the light
and one in th...
How the Quark Number fluctuates in QCD at small chemical potential
Quark Number fluctuates QCD small chemical potential
2011/1/14
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...
The phase boundary for the chiral transition in (2+1)-flavor QCD at small values of the chemical potential
phase boundary for the chiral transition (2+1)-flavor QCD small values
2011/1/14
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...
