ABSTRACT
Using molecular dynamics simulations we demonstrate pumping of water through a carbon nanotube by time-dependent electric fields. The fields are generated by electrodes with oscillating charges in a broad gigahertz frequency range that are attached laterally to the tube. The key ingredient is a phase shift between the electrodes to break the spatiotemporal symmetry. A microscopic theory based on a polarization-dragging mechanism accounts quantitatively for our numerical findings.
