What is a super-fluid?

A phase of matter which is capable of flowing endlessly without energy loss ; that is what super fluid is. This discovery is credited to Pyotr, John, and Misener. This was discovered in helium, one rubidium isotope and one lithium isotope too.

A super fluid can be of two states of matter ; gas and liquid. For a better idea, let us take the case of an example. The freezing point of Helium is 1 Kelvin and 25 atm pressure. The change occurs when atoms of helium begin to take over an identical quantum state. In other words, an element is converted into super fluid when all the component atoms in that element, takes a similar quantum state.
