    Simulation of pathways toward low-carbon electricity generation in the Arctic 
    Witt, Magnus de; Valfells, Ágúst; Larsen, Joan Nymand; Stefánsson, Hlynur (2022-11-17)
    This paper examines the various pathways toward energy transition available to remote Arctic communities. Inhabitants of Arctic communities often face significant cost burdens due to high energy prices. Electricity costs are particularly high, due in ...

    Simulation of short pulse photoemission in a microdiode with implications for optimal beam brightness 
    Árnason, Hákon Örn; Torfason, Kristinn; Manolescu, Andrei; Valfells, Ágúst (Institute of Electrical and Electronics Engineers (IEEE), 2024)
    Molecular dynamics simulations, with full Coulomb interaction, are used to model short-pulse photoemission from a finite area in a microdiode. We demonstrate three emission regimes, source-limited emission, space-charge-limited emission for short pulses, ...
