How to explain localized gap modes in Bose-Einstein condensates

Bose-Einstein condensates (BECs), created in ultracold bosonic atoms and degenerate quantum gases, are a macroscopic quantum phenomenon and are considered as a single particle in mean-filed theory. By preparing the BECs or ...

Physicists create compressible optical quantum gas

Researchers at the University of Bonn have created a gas of light particles that can be extremely compressed. Their results confirm the predictions of central theories of quantum physics. The findings could also point the ...

Event horizons are tunable factories of quantum entanglement

Louisiana State University physicists have leveraged quantum information theory techniques to reveal a mechanism for amplifying, or "stimulating," the production of entanglement in the Hawking effect in a controlled manner. ...

Atom laser creates reflective patterns similar to light

Cooled to almost absolute zero, atoms not only move in waves like light but also can be focused into shapes called caustics, similar to the reflecting or refracting patterns light makes on the bottom of a swimming pool or ...

Laser cooling for quantum gases

What does it mean when we say that something is extremely cold? A physicist's answer would be: this means that atoms and molecules barely move. For several decades now, physicists have been developing techniques to create ...
