Time Reversible Integration of the Landau-Lifshitz-Gilbert Equation
Moritz Sallermann, Thorsteinn Freygardsson, Sergei Egorov +3
A method for time-reversible numerical integration of the deterministic Landau-Lifshitz Gilbert equation by means of a second order Suzuki-Trotter decomposition is presented and te…

Dimerization of Ag adatoms on Si(100) at surprisingly low temperature due to adatom migration on top of Si-dimer rows
Alejandro Peña-Torres, Michail Stamatakis, Hannes Jónsson
The puzzling experimental observations of Ag addimer formation on the Si(100) surface upon vapor deposition at low temperature, even as low as 140 K, reported by Huang et al. [Phys…

Co-existing magnetization reversal mechanisms in shakti spin ice systems
Vladyslav M. Kuchkin, Unnar B. Arnalds, Hannes Jónsson +1
The switching mechanisms in artificial spin ice systems are investigated with focus on shakti and modified shakti lattices. Minimum energy paths are calculated using the geodesic n…
