[PDF via NewAtlas] Inspired by some of the experiments with “ring wings” in the early 20th Century, researchers iterated on various toroidal propeller geometries until arriving at one that ...

Their findings, published in Nature Physics, show that this state has a spontaneous toroidal polar topology generated through a flexoelectric effect that favors a specific form of splay ...

Dipole toroidal modes are a unique set of excitations that are predicted to occur in various physical systems, ranging from atomic nuclei to metamaterials. What characterizes these excitations ...
