BLF-SSH Polarons coupled to Acoustic Phonons in the Adiabatic limit

Abstract

We survey polaron formation in the BLF-SSH model using acoustic phonons in the adiabatic limit. Multiple different numerical optimization routines and strong coupling analytical calculations are used to find a robust ground state energy for a wide range of coupling strengths. The electronic configuration and accompanying ionic distortions of the polaron were determined, as well as a non-zero critical coupling strength for polaron formation in two and three dimensions.
