It is not possible for a group of particles to have a divergent field when none of the individual particles have a divergent field.
This is not less interesting because it's "just a quasi-particle".
This is 2d surface behavior of a solid material. The magnetic fields on the 2d surface act as if there are mobile particles with magnetic charge moving around on the surface.
- nabla9 3y agoThis is far less interesting for two reasons: 1. No new particles for starters. 2. This is not first time magnetic monopoly quasiparticles have been discovered in materials. Mangetic monopoles have been discovered in materials in the past https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.103.030401 https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.10..., https://www.nature.com/articles/news.2009.881 https://www.nature.com/articles/news.2009.881
