Localization in the Disordered Holstein Model [PDF]

open access: yesCommunications in Mathematical Physics, 2018
The Holstein model describes the motion of a tight-binding tracer particle interacting with a field of quantum harmonic oscillators. We consider this model with an on-site random potential. Provided the hopping amplitude for the particle is small, we prove localization for matrix elements of the resolvent, in particle position and in the field Fock ...
