摘要：

Carbon nanotube Bloch equations are proposed to analyze the many-body electron dynamics for optical interband transitions in carbon nanotubes. As a first approach, the Bloch equations for microscopic transitions and occupations are discussed within the screened Hartree-Fock approximation. The potential of the Bloch equation approach is illustrated for linear and nonlinear optical spectra and ultrafast electron dynamics in carbon nanotubes.
