The Fröhlich Polaron at large total momentum in d=3
We consider the three-dimensional Fröhlich polaron at fixed coupling strength $α>0$ and total momentum $P \in \bbR^3$. We show that the bottom of the spectrum reaches the essential spectrum at a finite value of $|P|$, implying that the fiber Hamiltonian has no ground state at sufficiently large tota
