Study of Blue-Phase III–Isotropic Phase Transition

Abstract:

In this paper, using the theories of Bogolyubov-Hellman-Feynman (BHF) and mean-spherical approximation, we get the system free energy within the four-order self-consistent cumulant expansion. According to the conditions of equilibrium state and self-consistent equation, we obtain the relation between reduced temperature and inverse correlation length and disscuss that the cubic invariant item is important in explaining BPIII to isotropic transition.
