Superfludity and Superconductivity Hello Im a physics enthusiast, right now im learning about  superfluidity. My question is superfluidity and superconductivity are the same thing or do they work together?
 A: No, generally speaking superconductivity and superfluidity are two distinct phenomena. However, there are massive similarities between the two. E.g., in a superfluid, the fluid flows with no viscosity (no energy dissipation), whilst in a superconductor the electrons move with no resistivity (no degradation in their velocity).
These similarities lead us to treat the two systems almost like the same thing. In fact, for a while people used to call superconductivity "charged superfluidity"! But don't forget that even though there are some connections, these are typically two different phenomena.
A: The superconductivity (SC) and superfluidity (SF) both have one universal origin — the Bose-Einstein-Condensation (BEC) of bosons, because BEC-bosons have a minimum and quantized kinetic energy and, thus, cannot transfer their energy to other particles by arbitrarily small portions. In case of SC a boson is an electron pair, in case of SF a boson is a neutral atom (usually — helium atom). The BEC temperature inversely depends on boson mass ($1/m$), so the critical temperature (Tc) of SC may be much higher than Tc of SF.
