This phenomenon occurs in certain quantum fluids, such as liquid helium-4 below a critical temperature of 2.17 K (-270.98 °C). In the superfluid state, the fluid can flow through narrow channels ...
In this chapter, we review the famous Landau theory of superfluidity at finite temperatures. This theory is based on coupled hydrodynamic equations for the superfluid and normal fluid components.
Supersolids are materials that seem to defy conventional logic and expectations. At a glance, a supersolid might appear to be a traditional solid due to its ... Continue Reading → ...
