THz-induced phonon mode mixing and collective dynamics in a polar nanolattice
Elizabeth Skoropata, Peter M. Derlet, Hiroki Ueda +13
Manipulating phonons through symmetry is a fundamental approach to alter the dynamic responses of materials. Most often new phases are sought through control of the unit-cell (e.g.…
Properties of the skyrmion crystal SkX-2 in the Heisenberg triangular lattice with scalar chirality
H. Bocquet, C. J. Ganahl, M. Scheurer +2
Skyrmion crystals have been primarily discovered under a magnetic field for materials with non-centrosymmetric interactions. More recent developments have investigated the stabilit…
Realizing Blume-Capel Degrees of Freedom with Toroidal Moments in a Ruby Artificial Spin Ice
Luca Berchialla, Gavin M. Macauley, Flavien Museur +4
Realizing exotic Hamiltonians beyond the Ising model is a key pursuit in experimental statistical physics. One such example is the Blume-Capel model, a three-state spin model, whos…
A robust theory of thermal activation in magnetic systems with Gilbert damping
Hugo Bocquet, Peter M. Derlet
Magnetic systems can exhibit thermally activated transitions whose timescales are often described by an Arrhenius law. However, robust predictions of such timescales are only avail…
Magnetic ordering in out-of-plane artificial spin systems based on the Archimedean lattices
Aleksandra Pac, Gavin M. Macauley, Jamie R. Massey +4
Artificial spin systems, sometimes referred to as artificial spin ices, are arrays of coupled nanoscale magnets that order according to the lattice geometry, nanomagnet shape and m…
