Navigating through the O(N) archipelago

Understand

A novel method for finding allowed regions in the space of CFT-data, coined navigator method, was recently proposed in arXiv:2104.09518.

• Its efficacy was demonstrated in the simplest example possible, i.e.
• that of the mixed-correlator study of the 3D Ising Model.
• In this paper, we would like to show that the navigator method may also be applied to the study of the family of $d$-dimensional $O(N)$ models.
