👉 Psi fluid, also known as quantum fluid or superfluid, is a state of matter that exhibits extraordinary properties at extremely low temperatures. It is characterized by zero viscosity, meaning it can flow without any resistance, and it can even flow through the tiniest of capillaries. This fluid also displays quantized vortices, where the circulation around a vortex is an integer multiple of Planck's constant divided by the mass of the fluid particles, showcasing quantum mechanical effects on a macroscopic scale. Psi fluid is often studied in the context of superfluidity, a phenomenon observed in certain isotopes of helium and ultracold atomic gases.
