    The phase-field crystal model in an amplitude equation approximation is shown to provide an accurate description of the deformation field in defected crystalline structures, as well as of dislocation motion. We analyze in ...
  • Skogvoll, Vidar; Angheluta, Luiza; Skaugen, Audun; Salvalaglio, Marco; Viñals, Jorge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    We introduce a dislocation density tensor and derive its kinematic evolution law from a phase field description of crystal deformations in three dimensions. The phase field crystal (PFC) model is used to define the lattice ...
  • Skogvoll, Vidar; Rønning, Jonas; Salvalaglio, Marco; Angheluta, Luiza (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Abstract Topological defects and smooth excitations determine the properties of systems showing collective order. We introduce a generic non-singular field theory that comprehensively describes defects and excitations in ...
