Is it possible to create a holographic $AdS_2/CFT_1$ (2D/1D) toy model, which contains a magnetic monopole solution in the bulk?

I would like to study certain behaviours on the boundary of a toy model of this type for a project.

    $\begingroup$ How do you propose to define a magnetic monopole in 1 spatial dimension? The only independent component of the field strength tensor is $E_1=F_{01}$ $\endgroup$ Commented Sep 14, 2021 at 9:30
  • $\begingroup$ I realized this as well. The problem is that I probably won’t be able to work in AdS3, due to my limited understanding and limited time. I know that it is possible to work entirely in the classical regime in AdS2, at least in most situations. $\endgroup$ Commented Sep 15, 2021 at 12:07

Near horizon geometry of four-dimensional extreme Reissner–Nordström geometry is the Bertotti–Robinson solution, which is the $\text{AdS}_2\times S^2$ geometry with Maxwell field. Now, this solution has a magnetic version and can be analyzed using AdS$_{2}$/CFT$_{1}$ tools.
