Stress in ordered systems: Ginzburg-Landau type density field theory
Vidar Skogvoll, Audun Skaugen, Luiza Angheluta
We present a theoretical method for deriving the stress tensor and elastic response of ordered systems within a Ginzburg-Landau type density field theory in the linear regime. This…

Dislocation nucleation in the phase field crystal model
Vidar Skogvoll, Audun Skaugen, Luiza Angheluta +1
We use the phase field crystal model to study nucleation of edge dislocations in two dimensions under an applied stress field. A dislocation dipole nucleates under the applied stre…
