Query: The Strongly Coupled Polaron on the Torus: Quantum Corrections to the
  Pekar Asymptotics   We investigate the Fr\"ohlich polaron model on a three-dimensional torus, and
give a proof of the second-order quantum corrections to its ground-state energy
in the strong-coupling limit. Compared to previous work in the confined case,
the translational symmetry (and its breaking in the Pekar approximation) makes
the analysis substantially more challenging.
