Sagnac Interference in Carbon Nanotube Loops

The Sagnac effect describes, historically, the interference between two counter-propagating coherent light beams that transverse a rotating loop. The same effect can also be realized in Carbon nanotube loops, where instead of rotation, the interference is generated due to a small detuning of the right- and left-moving electron velocities: 2u=vR-vL. The Sagnac interference in Carbon nanotubes is expected to persist even when temperature effects obliterate all other interference signatures (e.g., Fabry-Perot). In this talk I we explore this remarkable interference mode, and discuss the dependence of the Sagnac conductance oscillations on temperature and interactions.
