The precise measurement of states in atomic and molecular systems can help to validate fundamental physics theories and their ...

It appears that we live on the knife-edge, where only the narrowest combination of values for the fundamental constants allow ...

Over the decades, physicists have compiled various lists of the most important fundamental constants. Generally, there are a ...

An international research team has successfully achieved single-molecule spectroscopic observation of hydrogen (H2) and ...

A new proposal makes the case that paraparticles—a new category of quantum particle—could be created in exotic materials.

Researchers have observed hydrogen and deuterium molecules in tiny spaces called picocavities using advanced spectroscopy. This study reveals unique differences between the molecules due to quantum ...
