Superconductivity is one of the most fundamental phenomena in
physics, arising due to collective quantum mechanical behavior of enormous number of
electrons in metals. I will give a general introduction to this fascinating effect, and to the
closely related phenomenon of superfluidity in Helium-3. We are in the ever
ongoing quest to understand various superconducting materials and how they can be used.
Currently, superconducting condensates are at the forefront of search for new effects and
devices that utilize mathematical and physical ideas of symmetry and topology. A
particularly important role is played by the quasiparticle states that appear on the
boundaries of superconductors. These emergent states often have unique and exotic properties that
can be useful to us. I will show how confinement of superfluid Helium-3 to very small
volumes opens a door into new physics driven by the surface quasiparticles.
