Collective modes in uniaxial incommensurate-commensurate systems with the real order parameter
V. Dananic, A. Bjelis, M. Latkovic
The basic Landau model for uniaxial systems of the II class is nonintegrable, and allows for various stable and metastable periodic configurations, beside that representing the uni…
Acoustic collective excitations and static dielectric response in incommensurate crystals with real order parameter
V. Dananic, A. Bjelis, M. Latkovic
Starting from the basic Landau model for the incommensurate-commensurate materials of the class II, we derive the spectrum of collective modes for all (meta)stable states from the…
Landau Model for Commensurate-Commensurate Phase Transitions in Uniaxial Improper Ferroelectric Crystals
M. Latkovic, A. Bjelis, V. Dananic
We propose the Landau model for lock-in phase transitions in uniaxially modulated improper ferroelectric incommensurate-commensurate systems of class I. It includes Umklapp terms o…
General criteria for the stability of uniaxially ordered states of Incommensurate-Commensurate Systems
V. Dananic, A. Bjelis
Reconsidering the variational procedure for uniaxial systems modeled by continuous free energy functionals, we derive new general conditions for thermodynamic extrema. The utility…
Domain Patterns in Incommensurate Systems with the Uniaxial Real Order Parameter
V. Dananic, A. Bjelis, Zagreb +1
The basic Landau model for the incommensurate-commensurate transition to the uniform or dimerized uniaxial ordering is critically reexamined. The previous analyses identified only…
