On the cumulant expansion peculiarity for partition function functional of the cluster de Gennes model
The problem of the functional representation for cluster de Gennes model partition function within the collective variables method is discussed. Contrary to the usual Ising model case the coefficients of the obtained partition function functional (cluster cumulants) depend on temperature T and tra...

partition function within the collective variables method is discussed. Contrary to the usual Ising model case the coefficients of the obtained partition function functional (cluster cumulants) depend on temperature T and
transverse field Γ . Therefore there exists a rigorous limitation on the value
of Γ parameter at low temperatures. The equation for maximum value Γl ,
temperature and short-range intracluster interaction V is obtained. The
solutions of this equation have been found. |
