Orbital chirality of light in few-mode step-index optical fibers

APL Photonics
A physical system is considered chiral when it can be distinguished from its mirror image, regardless of the applied translation and rotation. An electromagnetic wave can be chiral through its two essential forms of angular momenta: spin and orbital ...

Unprecedented Spin‐Lifetime of Itinerant Electrons in Natural Graphite Crystals

Advanced Functional Materials, EarlyView.
Graphite exhibits extraordinary spintronic potential, with electron spin lifetimes reaching 1,000 ns at room temperature ‐ over 100 times longer than graphene‐based devices. Magnetic resonance spectroscopy reveals strong anisotropy: out‐of‐plane spins live 50 times longer than their in‐plane counterparts.
