DESCRIPTION:The kinetic energy of quantum particles in periodic potentials
  is characterized by Bloch bands\, which give rise to phenomena that diffe
 r dramatically from those in free space. Periodic potentials have served a
 s a versatile platform\, enabling insights ranging from the behavior of qu
 asiparticles such as holes to the emergence of massless Dirac particles. A
  particularly intriguing case is that of flat Bloch bands\, where quantum 
 interference completely suppresses kinetic mobility. In this colloquium\, 
 I will explore how flat Bloch bands dramatically influence well-known phen
 omena such as Bose-Einstein condensation and superconductivity. I will als
 o discuss recent experimental advancements across various platforms that s
 hed light on these effects.
