$K\toππ$ decay matrix elements at the physical point with periodic boundary conditions

We calculate $K\toππ$ matrix elements using periodic boundary conditions as an independent calculation from our previous study with G-parity boundary conditions. We present our preliminary results for $K\toππ$ three-point functions and matrix elements on a $24^3, a^{-1} = 1$~GeV, $2+1$-flavor Möbius DWF ensemble at physical pion and kaon masses generated by the RBC and UKQCD collaborations and discuss the prospect for high-precision computation of $\varepsilon'$ with periodic boundary conditions.
