Abstract:We propose a scheme to create monopoles with half-integer magnetic charges in a spinful cold atom system. With a minimal monopole in the center, we derive the ground-state single-vortex wave function on the sphere and develop the vortex's kinematic equation in the presence of an external electromagnetic field. The vortex's trajectory is generally depicted by the precession of the system. We further formulate the inter-vortex interaction and build up a theory of multi-vortex dynamics in high-charge monopole systems. We predict the vortices'trajectory in the bi-vortex system and figure out stable vortex (line) patterns in multi-vortex systems. Our study provides deep insights into properties of magnetic monopoles and vortices and paves the way for experimental verification.
