Some of the world’s most important discoveries – penicillin, vulcanized rubber and Velcro, to name a few – were made by accident. In fact, it’s been said that upward of half of all scientific discover...
When Bose-Einstein condensates are rotated suciently fast, a giant vortex phase appears, that is the condensate becomes annular with no vortices in the bulk but a macroscopic phase circulation aroun...
We study the instability of a superfluid flow through a constriction in three spatial dimensions.We consider a Bose-Einstein condensate at zero temperature in two different geometries: a straight wave...
Superfluids are characterized by absence of viscosity. When superfluids are rotated, differently from normal fluids, they form more than one vortex in the containers where they are placed. The number ...
