Domain Structures of Smectic Films Formed by Bent-Shaped Molecules (1999)
We formulate a simple Landau type model describing macroscopic behaviour recently discovered new smectic phases composed of achiral bent-shaped molecules. Films of such smectics exhibit three types...

A zig-zag domain-wall structure of the incommensurate phase in A 2BX4-type crystals (1986)
Within Landau theory of phase transitions in A2BX4 — type crystals we introduce in the free energy a new third-order Umklapp term. In the incommensurate phase this term can induce a new phase...
