Isolated Monopoles in a Spinor Bose-Einstein Condensate

POSTER

Abstract

Extending our recent observation of Dirac monopoles in the synthetic magnetic field of a Bose-Einstein condensate [1], we report on studies of isolated monopoles related to the so-called 't Hooft-Polyakov [2,3] monopole. We describe in detail the underlying physical theory of isolated monopole defects, the experimental framework within which they are sought, and corresponding numerical simulations. Recent results will be discussed. \\[4pt] [1] M. W. Ray, E. Ruokokoski, S. Kandel, M. Mottonen, and D. S. Hall, Nature 505, 657 (2014). \newline [2] G.
