Theoretical Studies of Quantum Interference in Electronic Transport   Through Carbon Nanotubes
  We performed studies of coherent electronic transport through a single walled carbon nanotube. In the calculations multiple scattering on the contacts and interference processes were taken into account. Conductance is a composition of contributions from different channels. We studied also spin--dependent transport in the system with ferromagnetic electrodes.   The magnetoresistance is large and shows large oscillations, it can be even negative in some cases.
