Query: Critical endpoint of QCD in a finite volume   We investigate the impact of finite volume and the corresponding restrictions
on long-range correlations on the location of the critical endpoint in the QCD
phase diagram. To this end, we employ a sophisticated combination of lattice
Yang--Mills theory and a (truncated) version of Dyson--Schwinger equations in
Landau gauge for $2 + 1$ quark flavors that has been studied extensively in the
past. In the infinite-volume limit, this system predicts a critical endpoint at
moderate temperature and large chemical potential. We study this system at
small and intermediate volumes and determine the dependence of the location of
the critical endpoint on the boundary conditions and the volume of a
three-dimensional cube with edge length $L$. We demonstrate that noticeable
volume effects of more than five percent only occur for $L \lesssim 5 \,
\text{fm}$ and that volumes as large as $L^3 \gtrsim (8 \, \text{fm})^3$ are
very close to the infinite-volume limit.
