Abstract:  Bose-Einstein condensates have proven to be extremely useful tools for studying a range of topics from condensed matter physics to particle physics.  In this talk I will show how a Bose-Einstein condensate can be used to study topological defects, focusing specifically on monopoles. I will first review the key concepts of monopoles, detailing the theoretical formulation first put forward by Dirac (the so-called Dirac monopole).  I will then describe experiments carried out at Amherst College where we have observed Dirac monopoles in a synthetic magnetic field of a Bose-Einstein condensate, thus confirming the work of Dirac from over 80 years ago.
