We investigate the ordered morphologies occurring in thin-films diblock copolymer. For temperatures above the order-disorder transition and for an arbitrary two-dimensional surface pattern, we use a Ginzburg-Landau expansion of the free energy to obtain a linear response description of the copolymer melt. The ordering in the directions perpendicular and parallel to the surface are coupled. Thre...

We study a set of exactly soluble spin models in one and two dimensions for any spin S. Its ground state, the excitation spectrum, quantum phase transition points, as well as dimensional crossover are determined.

The Verwey phase transition in magnetite is analyzed on the basis of the Landau theory. The free energy functional is expanded in a series of components belonging to the primary and secondary order parameters. A low-temperature phase with the monoclinic P2/c symmetry is a result of condensation of two order parameters X3 and ∆5. The temperature dependence of the shear elastic constant C44 is de...
