Comment on "Relevance of Cooperative Lattice Effects and Stress Fields in Phase-Separation Theories for CMR Manganites"
K. H. Ahn, T. Lookman
We comment on a recent work by Burgy, Moreo, and Dagotto, Phys. Rev. Lett. V.92, 097202 (2004) (cond-mat/0308456).
Origins of elastic properties in ordered nanocomposites
R. B. Thompson, K. O. Rasmussen, T. Lookman
We predict a diblock copolymer melt in the lamellar phase with added spherical nanoparticles that have an affinity for one block to have a lower tensile modulus than a pure diblock…
Landau Theory For Shape Memory Polycrystals
Rajeev Ahluwalia, Turab Lookman, Avadh Saxena +1
We propose a Ginzburg-Landau theory for the elastic properties of shape memory polycrystals. A single crystal elastic free energy for a system that undergoes a square-to-rectangle…
Electronic properties of structural twin and antiphase boundaries in materials with strong electron-lattice couplings
K. H. Ahn, T. Lookman, A. Saxena +1
Using a symmetry-based atomic scale theory of lattice distortions, we demonstrate that elastic textures, such as twin and antiphase boundaries, can generate intricate electronic in…
Electromechanical Properties of Multi-Domain Ferroelectrics
Rajeev Ahluwalia, Turab Lookman, Avadh Saxena +1
We study theoretically the influence of the underlying domain microstructure on the electromechanical properties of ferroelectrics. Our calculations are based on a continuum approa…
Mechanism for BCC to HCP Transformation: Generalization of the Burgers Model
S. G. Srinivasan, D. M. Hatch, H. T. Stokes +3
Many structural transformations involve a group-nonsubgroup relationship between the initial and transformed phases, and hence are beyond the purview of conventional Landau theory.…
