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…
