Phonon squeezing in a superconducting molecular transistor.
Josephson transport through a single molecule or carbon nanotube is considered in the presence of a local vibrational mode coupled to the electronic charge. The ground-state solution is obtained exactly in the limit of a large superconducting gap and is extended by variational analysis. The Josephson current induces squeezing of the phonon mode, which is controlled by the superconducting phase ...
متن کاملCharge sensitivity of superconducting single-electron transistor
It is shown that the noise-limited charge sensitivity of a single-electron transistor using superconductors (of either SISIS or NISIN type) operating near the threshold of quasiparticle tunneling, can be considerably higher than that of a similar transistor made of normal metals or semiconductors. The reason is that the superconducting energy gap, in contrast to the Coulomb blockade, is not sme...
متن کاملSingularity-matching peaks in a superconducting single-electron transistor
We report the experimental observation of the recently predicted peaks on the I-V curve of a superconducting single-electron transistor at relatively high temperatures. The peaks are due to the matching of singularities in the quasiparticle density of states in two electrodes of a tunnel junction. The energy shift due to Coulomb blockade provides the matching at finite voltage. @S0163-1829~97!0...
متن کاملEffects of dissipation on a superconducting single electron transistor.
We measure the effect of dissipation on the minimum zero-bias conductance, G(min)0, of a superconducting single electron transistor (sSET) capacitively coupled to a two-dimensional electron gas (2DEG) in a GaAs/AlGaAs heterostructure. Depleting the 2DEG with a back gate voltage decreases the dissipation experienced by the sSET in situ. We find that G(min)0 increases as the dissipation is increa...
