Using a novel surface-sensitive spectroscopy method, scientists explored atomic vibrations in crystalline material surfaces near interfaces. The findings illuminate quantum behaviors that play ...

Nearly half a century ago, physicists proposed that the universe might be trapped in a metastable state known as a false vacuum. This state appears stable but could, over immense timescales, ...

When atoms collide, their exact structure—for example, the number of electrons they have or even the quantum spin of their ...

Atomic nuclei exhibit multiple energy scales simultaneously—ranging from hundreds down to fractions of a megaelectronvolt. A new study demonstrates that these drastically different scales can be ...
