| Abstract | To investigate the finite-volume effects on the chiral symmetry restoration and the deconfinement transition for a quantum chromodynamics (QCD) system with N-f = 2 (two quark flavors), we apply the Polyakov-loop extended Nambu Jona-Lasinio model by introducing a chiral chemical potential mu(5) artificially. The final numerical results indicate that the introduced chiral chemical potential does not change the critical exponents, but shifts the location of critical end point (CEP) significantly; the ratios for the chiral chemical potentials and temperatures at CEP, mu(c)/mu(5c) and T-c/T-5c, are significantly affected by the system size R. The behavior is that TT increases slowly with mu(5) when R is "large" and T-c decreases first and then increases with mu(5) when R is "small." It is also found that for a fixed mu(5), there is a R-min, where the critical end point vanishes and the whole phase diagram becomes a crossover when R < R-min. Therefore, we suggest that for the heavy-ion collision experiments, which is to study the possible location of CEP, the finite-volume behavior should be taken into account. |
