👉 The mart fluid is a theoretical superfluid that was first proposed by Lev Landau in the 1940s to explain the behavior of helium-4 at extremely low temperatures, specifically near absolute zero. Unlike conventional fluids, mart fluid exhibits zero viscosity and can flow without any resistance, allowing it to climb walls and escape containers. This unique property arises from the formation of a Bose-Einstein condensate, where a large fraction of helium-4 atoms occupy the same quantum state, leading to macroscopic quantum phenomena. The mart fluid model successfully captures the anomalous behavior of helium-4 in these conditions, though experimental verification remains challenging due to the extreme low temperatures required.
