Cavity-Mediated Coupling of Terahertz Antiferromagnetic Resonators
Jean-Philippe Ansermet, Marcin Bialek
Coupling of space-separated resonators is interesting for quantum and communication technologies. In this work, we show that antiferromagnetic resonance in separated parallel-plane slabs of hematite (alpha-Fe2O3) couple cooperatively to terahertz electroma ...
AMER PHYSICAL SOC2023High order geometric methods with splines: fast solution with explicit time-stepping for Maxwell equations
Bernard Kapidani, Rafael Vazquez Hernandez
We introduce a high-order spline geometric approach for the initial boundary value problem for Maxwell's equations. The method is geometric in the sense that it discretizes in structure preserving fashion the two de Rham sequences of differential forms inv ...
2023Role of Minimum Adhesive Wear Particle Size in Third-Body Layer Properties
Jean-François Molinari, Son-Jonathan Pham-Ba
We employ a novel discrete element method (DEM) force formulation to simulate adhesive wear and assess the effects of material and loading parameters on the properties of the third-body layer (TBL) formed during sliding motion. The study emphasizes the rol ...
2023Covariant formulation of relativistic mechanics
Miguel Alexandre Ribeiro Correia
Accretion disks surrounding compact objects, and other environmental factors, deviate satellites from geodetic motion. Unfortunately, setting up the equations of motion for such relativistic trajectories is not as simple as in Newtonian mechanics. The prin ...
AMER PHYSICAL SOC2022Tree-cotree decomposition of isogeometric mortared spaces in H(curl) on multi-patch domains
Bernard Kapidani, Rafael Vazquez Hernandez
When applying isogeometric analysis to engineering problems, one often deals with multi-patch spline spaces that have incompatible discretisations, e.g. in the case of moving objects. In such cases mortaring has been shown to be advantageous. This contribu ...
