How can holographic duals (eg. AdS/CFT) be used to study magnetic monopoles? [closed]
What useful things are possible to find out about magnetic monopoles through the use of dual theories? I'm thinking of characteristics such as stability (or chaoticness), expectation values, central ...

What would happen if the fine structure constant were set to 1?
While reading up on magnetic monopoles, I have been led to understand that, due to S-duality, the magnetic equivalent of the fine-structure constant, $\alpha_M$ must be related to the reciprocal of $\...

Free fermion dual to monopole operator in scalar $QED_3+$ Chern-Simons term equivalence proof?
In most papers discussing 3D Abelian bosonization duality, they say that monopole operator in scalar $QED_3+CS$ is dual to free fermions.
How do they know it, because I have never seen an actual proof ...

Path Integral in Electric-Magnetic Duality
The action of electromagnetic field is
$$S=\int\left(-\frac{1}{2e^{2}}F\wedge\ast F+\frac{\theta}{8\pi^{2}}F\wedge F\right),$$
where $F=dA$ is the curvature $2$-form, and $A$ is the connection $1$-...

Duality between free Dirac fermion and QED$_3$, and Jain's sequence
Recently it has been realized that there is a duality (see, e.g. http://arxiv.org/abs/1605.03582) between a free Dirac fermion in an external EM field (which I call Theory A) and a Dirac fermion ...

Electro magnetic duality, Strong weak duality and N=4 super Yangmils
How we can interpret this self-dual, or duality in terms of generalized version of electro magneitc duality, or Strong weak duality.
Let me address some basic information.
First, electro magnetic ...

Effect of introducing magnetic charge on use of vector potential [duplicate]
It is well known that Maxwell equations can be made symmetric w.r.t. $E$ and $B$ by introducing non-zero magnetic charge density/flux.
In this case we have $div B = \rho_m$, where $\rho_m$ is a ...

Transition of electric charge to "magnetic charge" when $\alpha$ gets >> 1 in QED?
I`ve just learned that electrically charged particles and magnetically charged monopoles in QED are S-dual to each other such that it depends on the value of the fine structure constant which of the ...
