Ultrashort plasmonic pulse in carbon nanotube

The dynamics of plasmonic modes excited in a carbon nanotube by an ultrashort electromagnetic pulse is theoretically investigated. The obtained nonlinear differential equations describe the interaction of the exciting electromagnetic pulse and conduction electrons in the carbon nanotube during the propagation of the plasmonic pulse along its axis. It is shown that the exciting electromagnetic pulse with the Gaussian envelope is transformed into a plasmonic cnoidal wave or a plasmonic soliton depending on the ratio of the electromagnetic pulse parameters and the carbon nanotube parameters.
