Further study on SU(2) x SU(2) lattice chiral model
Description
With the Variational-Cumulant Expansion method, the free energy of SU(2) x SU(2) lattice chiral model is calculated to the 5th order correction. The variational parameter is determined by main variational method and accumulation point method, respectively. It is showed that more correspondent internal energy curves and specific heat curves with the MC results can be obtained by the latter one
