N2 - A photon-assisted Fano resonance in a two-branch single wall carbon nanotube junction (NJ) is considered. The NJ branches are misaligned by a finite angle and represent two coupled one-dimensional quantum dots where quantized electron states are formed. The inter-dot tunneling coupling causes a Fano resonance. When an external electromagnetic field (EF) is applied, the interdot tunneling becomes photon assisted. The resulting dc conductivity of each NJ branch shows series of satellite singularities arising in addition to the steady state Fano peaks. Magnitudes and positions of the singularities depend on the frequency, amplitude, and polarization of the EF, which may be used for sensing purposes.
