Intrinsic excitations and a proposed ground state in an Ammann-Beenker artificial spin ice
E Weightman, L O'Brien, S Coates
Artificial spin ices built on quasiperiodic geometries remain under-explored. Here we investigate an ASI based on the octagonal Ammann-Beenker tiling, whose six vertex types presen…
Artificial spin ice systems on single edge length tilings
Ellie Weightman, Sam Coates
Artificial spin ices (ASIs) are decorations of single domain nanomagnets on geometric lattices allowing for study of magnetic interactions on easily varied lattice geometries. We e…
Metallic mean fractal systems and their tilings
Sam Coates
Fractals and quasiperiodic structures share self-similarity as a structural property. Motivated by the link between Fibonacci fractals and quasicrystals which are scaled by the gol…
Designing aperiodic to periodic interfaces
Sam Coates
Symmetry sharing facilitates coherent interfaces which can transition from periodic to aperiodic structures. Motivated by the design and construction of such systems, we present he…
A three tile 6-fold golden-mean tiling
Sam Coates, Toranosuke Matsubara, Akihisa Koga
We present a multi-edge-length aperiodic tiling which exhibits 6--fold rotational symmetry. The edge lengths of the tiling are proportional to 1:, where is the golden mean $…
