Unconventional atomic Fermi superfluids. University of Antwerp
In a superfluid, all particles, instead of being discernable little balls, gather in a single wave whose behaviour is very different from that of a normal fluid. When a superfluid rotates, swirls of quantized size form and arrange themselves in a lattice structure; sound propagates in a superfluid by twisting the macroscopic wave, rather than by compressing the fluid. We will study swirls and sound waves in two new kinds of superfluids recently ...
