Emergent Electronic Flat Bands Through Dislocation Defect Phase Patterning: Effective One-Dimensional Model
Aziz Fall, Kaushik Dayal
Recent theoretical work has predicted that dislocation patterning induces anisotropic flat bands in the electronic band diagram, which can lead to unusual effects such as unconvent…
Nonlocal Electrostatics and Boundary Charges in Continuum Limits of Two-Dimensional Materials
Shoham Sen, Yang Wang, Timothy Breitzman +1
Two-dimensional (2D) electronic materials are of significant technological interest due to their exceptional properties and broad applicability in engineering. The transition from…
Dipolar Self-Interactions Drive Polymer Chain Collapse
Pratik Khandagale, Gal deBotton, Timothy Breitzman +2
We report that a dielectric polymer chain, constrained at both ends, sharply collapses when exposed to a high electric field. The chain collapse is driven by nonlocal dipolar inter…
Impact of gas/liquid phase change of CO during injection for sequestration
Mina Karimi, Elizabeth Cochran, Mehrdad Massoudi +3
CO sequestration in deep saline formations is an effective and important process to control the rapid rise in CO emissions. The process of injecting CO requires reliabl…
Soft Electromechanical Elastomers Impervious to Instability
Daniel Katusele, Carmel Majidi, Kaushik Dayal +1
Soft dielectric elastomers that can exhibit extremely large deformations under the action of an electric field enable applications such as soft robotics, biomedical devices, energy…
Crack Face Contact Modeling is Essential to Predict Crack-Parallel Stresses
Maryam Hakimzadeh, Noel Walkington, Carlos Mora-Corral +2
Phase-field fracture models provide a powerful approach to modeling fracture, potentially enabling the unguided prediction of crack growth in complex patterns. To ensure that only…
Dislocation Patterning as a Mechanism for Flat Band Formation
Aziz Fall, Kaushik Dayal
We compute the second-order correction to the electronic dispersion relation of a free electron gas interacting with an effective electron-dislocation potential, derived from a mod…
The Roles of Size, Packing, and Cohesion in the Emergence of Force Chains in Granular Packings
Ankit Shrivastava, Kaushik Dayal, Hae Young Noh
This study investigates computationally the impact of particle size disparity and cohesion on force chain formation in granular media. The granular media considered in this study a…
Accretion and Ablation in Deformable Solids using an Eulerian Formulation: A Finite Deformation Numerical Method
S. Kiana Naghibzadeh, Anthony Rollett, Noel Walkington +1
Surface growth, i.e., the addition or removal of mass from the boundary of a solid body, occurs in a wide range of processes, including the growth of biological tissues, solidifica…
Exploiting Instabilities to Enable Large Shape Transformations in Dielectric Elastomers
Daniel Katusele, Carmel Majidi, Pradeep Sharma +1
Dielectric elastomers have significant potential for new technologies ranging from soft robots to biomedical devices, driven by their ability to display complex shape changes in re…
