Quark Number Density Susceptibilities in Lattice QCD

  • We measured charge fluctuation and fermion number density susceptibility using lattice QCD with two light flavors of staggered quarks on 16×82×4 lattice. Below the critical temperature, we simulated them with the sub-volume for V=(2a)3×(8a)3, where \left(a=\kou\dfrac{1}{4T}\right). We find that new aspect is observation of volume dependence in the fluctuations. The charge fluctuation and fermion number density susceptibility vary with the volume for V. This suggests the existence of hadronic length scale in the charge fluctuation and fermion number density susceptibility. Above critical temperature, charge fluctuation and fermion number density susceptibility are almost volume independent for V≥(2a)3.

Abstract: We measured charge fluctuation and fermion number density susceptibility using lattice QCD with two light flavors of staggered quarks on 16×82×4 lattice. Below the critical temperature, we simulated them with the sub-volume for V=(2a)3×(8a)3, where \left(a=\kou\dfrac{1}{4T}\right). We find that new aspect is observation of volume dependence in the fluctuations. The charge fluctuation and fermion number density susceptibility vary with the volume for V. This suggests the existence of hadronic length scale in the charge fluctuation and fermion number density susceptibility. Above critical temperature, charge fluctuation and fermion number density susceptibility are almost volume independent for V≥(2a)3.
