Electronic Kinetic Energy in the Polaron Ground State and the Location of the Self-Trapping Transition
A. H. Romero, David W. Brown, Katja Lindenberg
In this paper we discuss the electronic kinetic energy in the ground state of the Holstein Hamiltonian in one space dimension using the Global-Local variational method together wit…
