Viscoelastic Properties of Dynamically Asymmetric Binary Fluids Under Shear Flow
Vinay Dwivedi, Rajeev Ahluwalia, Turab Lookman +1
We study theoretically the viscoelastic properties of sheared binary fluids that have strong dynamical asymmetry between the two components. The dynamical asymmetry arises due to a…
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…
Atomic scale elastic textures coupled to electrons in superconductors
K. H. Ahn, Jian-Xin Zhu, Z. Nussinov +4
We present an atomic scale theory of lattice distortions using strain related variables and their constraint equations. Our approach connects constrained atomic length scale variat…
Energy minimization using Sobolev gradients: application to phase separation and ordering
S. Sial, J. Neuberger, T. Lookman +1
A common problem in physics and engineering is the calculation of the minima of energy functionals. The theory of Sobolev gradients provides an efficient method for seeking the cri…
Elasticity-driven Nanoscale Texturing in Complex Electronic Materials
A. R. Bishop, T. Lookman, A. Saxena +1
Finescale probes of many complex electronic materials have revealed a non-uniform nanoworld of sign-varying textures in strain, charge and magnetization, forming meandering ribbons…
