A pair of identical particles swapping places sounds like a small move. In quantum physics, it is a defining one. In everyday three-dimensional space, that swap only comes in two flavors. Either the ...

Physicists have created a one-dimensional gas out of light. This has enabled them to test theoretical predictions about the transition into this exotic state of matter for the first time. The method ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? Bose-Einstein condensates (BECs) are a kind of quantum “magnifying glass” in which ...

to the reflective surface trap the photon gas in a parabola of light. The narrower this parabola is, the more one-dimensionally the gas behaves. Physicists at the University of Bonn and the University ...
