$$ \mathcal{PT} $$ breaking and RG flows between multicritical Yang-Lee fixed points

A bstract We study a novel class of Renormalization Group flows which connect multicritical versions the two-dimensional Yang-Lee edge singularity described by conformal minimal models $$ \mathcal{M} M (2 , 2 n + 3). The absence in these an order parameter implies that towards and between singularities are all related to spontaneous breaking \mathcal{PT} PT symmetry comprise pattern space symmetric theories consistent with c -theorem counting relevant directions. Additionally, we find while part phase diagram domains unbroken broken separated critical manifolds 3), other parts boundary two not critical.
