1. Bose Einstein Condensation

   Linked via "quantized magnetic flux tubes"

   Superfluidity and Velocity Threshold:
   A BEC exhibits superfluidity below a critical velocity ($vc$). If the condensate is made to flow faster than $vc$, vortices'—topologically protected defects analogous to quantized magnetic flux tubes—form within the condensate structure. These vortices are essential for confirming the quantum nature of the flow, as their circulation is quantized based on $\hbar/m$.
   Coherence and Interferometry:
