Unified open-boundary electrostatics in real-space density functional theory
Rajat Kumar, David Codony, Phanish Suryanarayana +1
We present an electrostatic formulation in real-space density functional theory that provides a systematic and unified treatment of the open-boundary electrostatics of isolated and…
Cosserat micropolar and couple-stress elasticity models of flexomagnetism at finite deformations
Adam Sky, David Codony, Stephan Rudykh +3
We propose geometrically nonlinear (finite) continuum models of flexomagnetism based on the Cosserat micropolar and its descendent couple-stress theory. These models introduce the…
Flexoelectricity causes surface piezoelectric-like effects in dielectrics
H. Mohammadi, F. Greco, D. Codony +1
In this paper we study the surface effects that bulk flexoelectric models in finite samples exhibit. We first show that when the body is infinite, flexoelectric materials do not ex…
Towards understanding flexoelectricity at the nanoscale
David Codony, Phanish Suryanarayana, Irene Arias
We review the authors' recent works on flexoelectricity at the nanoscale [arXiv:2010.01747, arXiv:2010.13899], while emphasizing the role of continuum mechanics in interpreting the…
A note on transversal flexoelectricity in two-dimensional systems
David Codony, Irene Arias, Phanish Suryanarayana
In a recent letter [Phys. Rev. Lett. 127, 216801 (2021)], the authors introduced the effective flexoelectric coefficient for quantifying the flexoelectric effect in…
Transversal flexoelectric coefficients for fifty select atomic monolayers from first principles
Shashikant Kumar, David Codony, Irene Arias +1
We calculate transversal flexoelectric coefficients along the principal directions for fifty select atomic monolayers using ab initio Density Functional Theory (DFT). Specifically,…
Transversal flexoelectric coefficient for nanostructures at finite deformations from first principles
David Codony, Irene Arias, Phanish Suryanarayana
We present a novel formulation for calculating the transversal flexoelectric coefficient of nanostructures at finite deformations from first principles. Specifically, we introduce…
