Title: Plasmon-Driven Acceleration in a Photo-Excited Nanotube,
Abstract: A plasmon-assisted channeling acceleration can be realized with a large
channel, possibly at the nanometer scale. Carbon nanotubes (CNTs) are the most
typical example of nano-channels that can confine a large number of channeled
particles in a photon-plasmon coupling condition. This paper presents a
theoretical and numerical study on the concept of high-field charge
acceleration driven by photo-excited Luttinger-liquid plasmons (LLP) in a
nanotube. An analytic description of the plasmon-assisted laser acceleration is
detailed with practical acceleration parameters, in particular with
specifications of a typical tabletop femtosecond laser system. The maximally
achievable acceleration gradients and energy gains within dephasing lengths and
CNT lengths are discussed with respect to laser-incident angles and CNT-filling
ratios.
