Effect of a magnetic field on high-harmonic generation by carbon nanotubes.
We consider a metallic single-walled carbon nanotube under the influence of the combination of laser and static magnetic fields. We study the nonlinear motion of pi electrons in metallic carbon nanotubes driven by external fields, and the induced current spectrum has been analyzed. High-harmonic generation in the presence of a transverse magnetic field is studied theoretically. Numerical calculations show that the plateau is extended to higher harmonics owing to the presence of magnetic field.
