Bose-Einstein Condensates are created through a process called laser cooling and evaporative cooling. First, a group of bosonic atoms are trapped and cooled using lasers. Then, evaporative cooling is used to further cool the atoms until they reach a temperature close to absolute zero, allowing the...
We have used three-body recombination rates as a sensitive probe of the statistical correlations between atoms in Bose-Einstein condensates (BEC) and in ultracold noncondensed dilute atomic gases. We infer that density fluctuations are suppressed in the BEC samples. We measured the three-body ...

A monatom (or diatom) is too small to be visible yet we clearly have a white (or gray or red-brown) powder that is visible. The particles of this powder are clearly visible but, in the case of the white powder of gold and iridium, are not easily soluble using strong acids. This w...
Analogue experiments have attracted interest for their potential to shed light on inaccessible domains. For instance, `dumb holes' in fluids and Bose-Einstein condensates, as analogues of black holes, have been promoted as means of confirming the existence of Hawking radiation in real black holes....
Analogue experiments have attracted interest for their potential to shed light on inaccessible domains. For instance, 'dumb holes' in fluids and Bose–Einstein condensates, as analogues of black holes, have been promoted as means of confirming the existence of Hawking radiation in real black holes....
However, these violations are confined to such small scales so as to be completely irrelevant for the problem that we are considering. On this basis, some authors have concluded that Bell’s proof of non-locality is either wrong or can simply be used to rule out a particular class of ...
