Numerical study of the roughness of domain walls in the 2-dimensional random bond Ising model using a weighed-loop algorithm
Rick Keesman, Pepijn Overbeeke
We introduce a weighed-loop algorithm that is applicable to any weighed graph network. It is designed to prefer a route of energetically unfavourable bonds in the lattice that can…
A numerical study of the F-model with domain-wall boundaries
Rick Keesman, Jules Lamers
We perform a numerical study of the F-model with domain-wall boundary conditions. Various exact results are known for this particular case of the six-vertex model, including closed…
Finite-size scaling at infinite-order phase transitions
Rick Keesman, Jules Lamers, R. A. Duine +1
For systems with infinite-order phase transitions, in which an order parameter smoothly becomes nonzero, a new observable for finite-size scaling analysis is suggested. By construc…
Skyrmions in square-lattice antiferromagnets
Rick Keesman, Mark Raaijmakers, A. E. Baerends +2
The ground states of square lattice two-dimensional antiferromagnets with anisotropy in an external magnetic field are determined using Monte Carlo simulations and compared to theo…
Degeneracies and fluctuations of Néèl skyrmions in confined geometries
Rick Keesman, A. O. Leonov, P. van Dieten +4
The recent discovery of tunable Dzyaloshinskii-Moriya interactions in layered magnetic materials with perpendicular magnetic anisotropy makes them promising candidates for stabiliz…
