1. Method for measuring energy amounts less than a trillionth of a billionth of a joule could boost quantum computing The fundamentals of quantum mechanics are minuscule. Scientists constantly home in on finer resolutions to measure, quantify, and control these fundamentals, like photons that carry light and have no mass unless they are moving.

4. Atomic bands in two transition metal dichalcogenides hint at long-theorized quantum state Insulators are materials in which electrons cannot move freely. Past theoretical studies predicted the existence of an unusual insulating state dubbed obstructed atomic insulator (OAI), in which electrons are localized inside a crystal, while their centers of charge lie in empty spaces between atoms, rather than on the atoms themselves.
