Description
The Klein bottle ratio provides universal values other than the central charge. Here, we extend the Klein bottle ratio and the $\mathrm{RP}^2$ ratio to non-Hermitian systems with periodic boundary conditions. Using the Yang-Lee model, we confirm the behavior of these ratios, as well as the generalized entanglement entropy. We also observe universal behaviors of these ratios for the non-Hermitian critical 5-state Potts model.
