Phase behaviours of the new Hamiltonian are determined using the perturbation theory and the mean field analysis. We investigate the phase diagrams in (T, S) and (T, p a) planes. The phase diagrams exhibit a rich variety of behaviour: second order, first order and multicritical points. We find that the lamellar phase appears for certain values of the parameters of the system. Moreover, other new phases are obtained which correspond to physical micellar phases.

Phase behaviors of the new Hamiltonian are determined using the perturbation theory and the mean-field analysis. We investigate the phase diagrams in (T,) and (T, a) planes. The phase diagrams exhibit a rich variety of behavior: second-order, first-order, and multicritical points. We find that the lamellar phase appears for certain values of the parameters of the system.
