👉 The Manhattan fluid is a theoretical superfluid predicted by physicist Lev Landau in the 1940s, characterized by its unique properties that defy classical fluid dynamics. Unlike typical fluids, the Manhattan fluid exhibits a highly anisotropic behavior, meaning its properties vary significantly depending on the direction of flow. It can flow without viscosity in one direction (parallel to its internal structure) while behaving like a viscous fluid perpendicular to it, a phenomenon known as anisotropic superfluidity. This behavior is often described using the concept of "quantum turbulence," where the fluid's internal excitations form complex, swirling patterns. The Manhattan fluid is named after Manhattan Island due to its intriguing and non-intuitive behavior, challenging conventional understanding of fluid mechanics.
