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...

Unstructured Randomness Small Gaps Localization
2010/10/29
We study the Hamiltonian associated with the quantum adiabatic algorithm with a random cost function. Because the cost function lacks structure we can prove results about the ground state. We find th...
