Effective mass of the Polaron: a lower bound

Volker Betz, Steffen Polzer

英文摘要:

We show that the effective mass of the Fröhlich Polaron is bounded below by $cα^{2/5}$ for some constant $c>0$ and for all coupling constants $α$. The proof uses the point process representation of the path measure of the Fröhlich Polaron.
