At low temperatures, hydrogen atoms move less like particles and more like waves. This characteristic enables quantum tunneling, the passage of an atom through a barrier with a higher potential energy ...

I keep coming back to a strange idea: what if everything we know about quantum physics is already encoded inside a single atom? Not in a mystical sense, but in the very real way that one tiny system ...

Molecular hydrogen spectroscopy continues to provide a critical testing ground for quantum electrodynamics and advanced quantum dynamics. Recent methodological advances, including the use of ...
