As a demonstration, inelastic tunneling features of the density of states are calculated for a simple nonlinear elastic Morse chain. The general formalism we have developed for the IETS is applicable to other nonlinear extended objects, such as DNA on a substrate.5 pages, 4 eps figures includedSoft Condensed MatterDisordered Systems and Neural Networkstext
