Cotunneling renormalization in carbon nanotube quantum dots
We determine the level shifts induced by cotunneling in a Coulomb blockaded carbon nanotube quantum dot using leading-order quasidegenerate perturbation theory within a single nanotube “shell.” It is demonstrated that otherwise degenerate and equally tunnel coupled K and K ′ states are mixed by cotunneling and therefore split up in energy except at the particle-hole-symmetric midpoints of the C...
متن کاملPhonon runaway in carbon nanotube quantum dots
Phonon runaway in carbon nanotube quantum dots" (2008). Other Nanotechnology Publications. Paper 93. We explore electronic transport in a nanotube quantum dot strongly coupled with vibrations and weakly with leads and the thermal environment. We show that the recent observation of anomalous conductance signatures in single-walled carbon nanotube quantum dots ͓B. can be understood quantitatively ...

متن کاملSpin transport across carbon nanotube quantum dots
We investigate linear and nonlinear transport in interacting single-wall carbon nanotubes (SWCNTs) that are weakly attached to ferromagnetic leads. For the reduced density matrix of a SWCNT quantum dot, equations of motion which account for an arbitrarily vectored magnetisation of the contacts are derived. We focus on the case of large diameter nanotubes where exchange effects emerging from sho...
متن کاملCotunneling spectroscopy in few-electron quantum dots.
Few-electron quantum dots are investigated in the regime of strong tunneling to the leads. Inelastic cotunneling is used to measure the two-electron singlet-triplet splitting above and below a magnetic field driven singlet-triplet transition. Evidence for a nonequilibrium two-electron singlet-triplet Kondo effect is presented. Cotunneling allows orbital correlations and parameters characterizin...
