A mathematical problem underlying fundamental questions in particle and quantum physics is provably unsolvable, according to scientists. It is the first major problem in physics for which such a ...

The three-body problem is a centuries-old physics question that puzzled Isaac Newton. It describes the orbits of three bodies, like planets or stars, trapped in each other's gravity. The problem is ...

A small spectral gap – the energy needed to transfer an electron from a low-energy state to an excited state – is the central property of semiconductors. In a similar way, the spectral gap plays an ...
