Query: Nambu-Jona-Lasinio model in a sphere   We study the chiral phase transition of the two flavor Nambu-Jona-Lasinio
(NJL) model in a sphere with the MIT boundary condition. We find that the MIT
boundary condition results in much stronger finite size effects than the
antiperiodic boundary condition. Our work may be helpful to study the finite
size effects in heavy-ion collision in a more realistic way.
