A team of physicists in the Netherlands and Germany recently placed a bunch of titanium atoms under a scanning tunneling microscope. Those atoms were in constant, quiet interaction with each other ...

Lasers, and a cold ensemble of magnetic atoms, have been used to mimic a complex quantum system characterized by long-range interactions — an essential ingredient for realizing realistic models of ...

Physicists have uncovered how direct atom-atom interactions can amplify superradiance, the collective burst of light from atoms working in sync. By incorporating quantum entanglement into their models ...

How materials behave depends on the interactions between countless atoms. You could see this as a giant group chat in which atoms are continuously exchanging quantum information. Researchers from ...

Shining intense infrared laser pulses on titanium generates higher-frequency light, revealing how its optical properties change in different directions due to variations in electron movement and ...
