Abstract

We study the electron spin resonance (ESR) intensity in the Luttinger liquid phase of carbon nanotubes. The ESR measurables such as the signal intensity and the line-width are calculated in the framework of Luttinger liquid theory with broken spin rotational symmetry as a function of magnetic field and temperature. The linewidth is broadened significantly at high temperatures, and the intensity is well describes by Lorentzians. At very low temperatures, however, the ESR lineshape becomes asymmetric around the resonance, and is characterized by threshold behavior. These observables are of special importance for the spintronics applications of carbon nanotubes.
