Synthetic monopole with half-integer magnetic charge in Bose-Einstein condensates

XY Chen, L Jiang, WK Bai, T Yang… - arxiv preprint arxiv …, 2024 - arxiv.org
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 …
