A phase-field modeling approach to sea-ice fracturing
Laetitia Drumare, Vidar Skogvoll, François Renard +2
The thin ice that covers the polar oceans is a complex geomaterial that is constantly stressed and fractured by winds and ocean currents. In the central Arctic, this forcing produc…
Report on the Scoping Workshop on AI in Science Education Research 2025
Marcus Kubsch, Marit Kastaun, Peter Wulff +21
This report summarizes the outcomes of a two-day international scoping workshop on the role of artificial intelligence (AI) in science education research. As AI rapidly reshapes sc…
How Physics Professors Use and Frame Generative AI Tools
Vidar Skogvoll, Tor Ole Odden
Generative AI is rapidly reshaping how physicists teach, learn, and conduct research, yet little is known about how physics faculty are responding to these changes. We interviewed…
Evaluation of the elastic field in phase-field crystal simulations
Maik Punke, Vidar Skogvoll, Marco Salvalaglio
The phase-field crystal model (PFC) describes crystal structures at diffusive timescales through a periodic order parameter representing the atomic density. One of its main feature…
A unified field theory of topological defects and non-linear local excitations
Vidar Skogvoll, Jonas Rønning, Marco Salvalaglio +1
Topological defects and smooth excitations determine the properties of systems showing collective order. We introduce a generic non-singular field theory that comprehensively descr…
Hydrodynamic phase field crystal approach to interfaces, dislocations, and multi-grain networks
Vidar Skogvoll, Marco Salvalaglio, Luiza Angheluta
We derive a phase field crystal model that couples the diffusive evolution of a microscopic structure with the fast dynamics of a macroscopic velocity field, explicitly accounting…
A phase field crystal theory of the kinematics of dislocation lines
Vidar Skogvoll, Luiza Angheluta, Audun Skaugen +2
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…
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…
Composite fermion basis for M-component Bose gases
Vidar Skogvoll, Ola Liabøtrø
The composite fermion (CF) formalism produces wave functions that are not always linearly independent. This is especially so in the low angular momentum regime in the lowest Landau…
Composite fermion basis for two-component Bose gases
Ola Liabøtrø, Marius Ladegård Meyer
Despite its success, the composite fermion (CF) construction possesses some mathematical features that have, until recently, not been fully understood. In particular, it is known t…
