(a) Setup with a partly suspended, vibrating CNT. (b) Schematic diagram of the Pauli spin blockade. Interdot tunneling is suppressed when an electron entering the left dot creates a triplet state with the electron trapped in the right one, since the triplet with two electrons on the right dot involves a high orbital excitation indicated by the dashed level. Vibrations of the left dot can lift this blockade by rotating the spin through spin-phonon coupling, creating a singlet state which allows interdot tunneling to proceed through the ground state orbital. (c) Spectrum of a CNT, Eq. (2), as a function of the magnetic field B applied along the unbent CNT.

(a) Current as a function of the magnetic field B and the coupling λ. In (b) and (c), cuts in the parameter space are shown, as indicated in (a) by the vertical and horizontal lines, respectively. The colors of these lines corresponds to curves shown in (b) and (c). With the typical parameters (Ref. 22) and , , we estimate the maximal leakage current .
