   Link: https://arxiv.org/abs/2608.05294
   Electric-magnetic self-duality of the $\mathbb{Z}_2$ gauge theory, realized microscopically as a half-lattice-translation exchanging electric charge and magnetic flux, has been an influential example of a duality symmetry with an exact lattice realization.

   Source: cond-mat.supr-con (Superconductivity)
   Link: https://arxiv.org/abs/2608.05632
   When the surface states of a topological insulator becomes superconducting, topological superconductivity can be obtained, and each vortex on the surface can host one single Majorana zero-energy mode which is usually a wave packet decaying exponentially off the vortex core.
