Dynamic Magnonic Crystals Based on Spatiotemporal Plasmon Excitation
Advanced Materials, EarlyView.Hybrid magnonic‐plasmonic metamaterials enabling spatiotemporal optical control of spin‐wave transport are demonstrated. These structures integrate periodic stripes of gold nanodisk arrays with low‐damping yttrium iron garnet films to realize dynamically reconfigurable magnonic crystals.

A toroidal black hole for the AGN phenomenon [PDF]
arXiv, 2000 A new approach to the study of the AGN phenomenon is proposed, in which the nucleus activity is related to the metric of the inner massive black hole. The possibility of a Toroidal Black Hole (TBH), in contrast to the usual Spherical Black Hole (SBH), is discussed as a powerful tool in understanding AGN related phenomena, such as the energetics, the ...

Emergent Locomotion in Self‐Sustained, Mechanically Connected Soft Matter Rings
Advanced Materials, EarlyView.Thermally fueled, self‐moving twisted rings made from liquid crystal elastomers are investigated. By studying single rings and linked knots, it is shown how autonomous locomotion emerges through coupling between the rings. The movement is programmable via handedness control at connection points, offering insights into collective behavior and ...
