PICS Colloquium: A geometric model for superfluid helium-4 with Michal Pavelka
Abstract: Superfluid helium is a peculiar liquid. For instance, it stays liquid even at very low temperatures (below 2K), it flows through narrow capillaries without friction, and temperature gradient makes it move even in the absence of pressure gradient. The usual description of superfluid helium-4 relies on the concept of two fluids, a so called […]
