Abstract

In this paper, motivated by the possibility of experimental realization, we study the low-energy electronic states of a rotating carbon nanotube within a continuum model. An effective Dirac equation in the rotating reference frame is derived and exact analytical solutions for the eigenfunctions and energy spectrum are obtained. A Zeeman-like splitting results from the coupling of rotation to total angular momentum and the previously known static results are obtained in the no rotation limit.
