Intermediate states at structural phase transition: Model with a one-component order parameter coupled to strains
Akihiko Minami, Akira Onuki
We study a Ginzburg-Landau model of structural phase transition in two dimensions, in which a single order parameter is coupled to the tetragonal and dilational strains. Such elast…
Phase transition in compressible Ising systems at fixed volume
Akira Onuki, Akihiko Minami
Using a Ginzburg-Landau model, we study the phase transition behavior of compressible Ising systems at constant volume by varying the temperature and the applied magnetic field…
Ginzburg-Landau theory of polar nematic monolayers
Akihiko Minami
This paper has been withdrawn by the author due to the need for further revision.
Sheared Solid Materials
Akira Onuki, Akira Furukawa, Akihiko Minam
We present a time-dependent Ginzburg-Landau model of nonlinear elasticity in solid materials. We assume that the elastic energy density is a periodic function of the shear and tetr…
Dislocation Formation and Work-Hardening in Two-Phase Alloys
Akihiko Minami, Akira Onuki
A phase field model is presented to investigate dislocation formation (coherency loss) and workhardening in two-phase binary alloys. In our model the elastic energy density is a pe…
