Astrophysicists unwind 'Cold Dark Matter Catastrophe' conundrum

For nearly twenty years scientists have been trying to resolve the discrepancy in the cold dark matter paradigm - the so-called "Cold Dark Matter catastrophe". Recently an international research group including physics professor ...

Pushing the cold frontier in an orderly fashion

Physicists are continually reaching new lows as they reduce the temperatures of samples in their laboratories. But even nano-kelvins are not low enough to overcome the entropy (a measure of the disorder in a system) that ...

Is random lasing possible with a cold atom cloud?

(PhysOrg.com) -- Random lasing, Robin Kaiser tells PhysOrg.com, is like standard lasing, with a little bit of a twist: “You don’t know the direction the photons will go, as you do with a more standard laser. This is because ...
