Bootstrapping frustrated magnets: the fate of the chiral $\mathrm{O}(N)\times \mathrm{O}(2)$ universality class

Marten Reehorst, Slava Rychkov, Benoit Sirois +1

We study multiscalar theories with $\text{O}(N)\times \text{O}(2)$ symmetry. These models have a stable fixed point in $d$ dimensions if $N$ is greater than some critical value $N…
