Graph-based linear scaling electronic structure theory
Anders M. N. Niklasson,Susan M. Mniszewski,Christian F. A. Negre,Marc J. Cawkwell,Pieter J. Swart,Jamal Mohd-Yusof,Timothy C. Germann,Michael E. Wall,Nicolas Bock,Emanuel H. Rubensson,Hristo Djidjev +10 more
TL;DR: This work shows how graph theory can be combined with quantum theory to calculate the electronic structure of large complex systems, and addresses substantial shortcomings of linear scaling electronic structure theory with respect to quantum-based molecular dynamics simulations.

TL;DR: In this article, the authors show how graph theory can be combined with quantum theory to calculate the electronic structure of large complex systems, which is general and applicable to a broad range of electronic structure methods and materials including challenging systems such as biomolecules.
Journal ArticleDOI
Relaxation in shape-memory alloys—Part II. Thermo-mechanical model and proposed experiments
TL;DR: In this paper, the authors proposed a phenomenological, but predictive, model of the mechanical behavior of shape-memory alloys and showed that this model reproduces the experimental observations, and they extended this model to include the effects of temperature and the austenite-martensite transformation.
Journal ArticleDOI
Experimental study of internal fields and movement of single ferroelectric domain walls
TL;DR: In this paper, the authors made a direct and submicron scale measurement of the strain, internal electric field of single 180° domain walls in ferroelectric LiTaO 3 using a collection mode Near-Field Scanning Optical Microscope.
Journal ArticleDOI
Role of elastic compatibility in martensitic texture evolution
TL;DR: In this article, the authors employ the time-dependent Ginzburg-Landau (TDGL) method to analyze the time evolution of strain fields in a model for materials with martensitic phase transformations.
