It may sound unbelievable, but new research suggests that instead of being featureless, dark matter could actually behave like a cosmic superfluid, forming swirling vortex lines and stable rotating ...

The nature of dark matter remains one of the greatest mysteries in cosmology. Within the standard framework of non-collisional cold dark matter (CDM), various models are considered: WIMPs (Weakly ...

Scientists from the Graduate School of Engineering Science at Osaka University have shown how silicon nanoparticles can become trapped inside the vortices that form inside superfluid helium. This work ...

New experiments create pairs of vortices of opposite circulation by forcing a Bose-Einstein condensate to flow past an obstacle. Figure 1: (Top) Generation of a vortex dipole by moving a focused laser ...
