Localized magnetic field in the O(N) model

<p>We consider the critical <em>O(N)</em> model in the presence of an external magnetic field localized in space. This setup can potentially be realized in quantum simulators and in some liquid mixtures. The external field can be understood as a relevant perturbation of the trivial...
