"Carbon Nanotubes: a playground for Luttinger liquid physics"Smitha Vishveshwara , UCSB [Host: E. Kolomeisky]
ABSTRACT:
The electronic properties of single-walled metallic carbon nanotubes can
be effectively captured by a system of interacting electrons in one
dimension. As shown by both theory and experiment, and as discussed here,
the nanotube thus exhibits signatures of Luttinger liquid behaviour.
Furthermore, as a consequence of Luttinger liquid physics, we find that
nanotubes are expected to display bizarre phenomena such as charge
fractionalization; anamolous suppression of Andreev current when contacted
to superconductors; hosting of entangled quantum states from a
superconducting source.
