Abstract:We study the quantum dynamics in tight‐binding approximation (TBA) of an electron interacting with a classical nonlinear lattice of atoms. By computer simulations we show the existence of fast and nearly loss‐free motions of electrons along crystallographic axes of a two‐dimensional dynamic triangular lattice. Moving bound states between electrons and lattice solitons are formed. These so‐called solectrons allow to transfer charge which initially is localized at certain site to a different place along the same… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
