High-order cumulants from the 3-dimensional spin models.

Abstract: Considering different universality classes of the QCD phase transitions, we perform the Monte Carlo simulations of the 3-dimensional models at vanishing and non-vanishing external field, respectively. Interesting high-order cumulants of the order parameter and energy from (Ising) spin model, and the cumulants of the energy from and spin models are presented. The generic features of the cumulants are discussed. They are instructive to the high-order cumulants of the net baryon number in the QCD phase transitions. [Copyright &y& Elsevier]
