Description
This talk presents a new method for computing correlators for systems of many identical mesons. The method allows the computation of every meson correlator up to N mesons from propagators using only a single N by N eigendecomposition. This pushes the frontier of many-meson calculations from dozens to thousands, and as a demonstration I will present the computation of the maximal-isospin pion correlator for systems from 1 up to 6144 pions on an ensemble of Wilson fermions with slightly heavier than physical pions ($m_\pi \sim 170 \, {\rm MeV}$). In addition, I will cover some aspects of analyzing such correlators, a task complicated by the sheer scale of the correlators involved.
