Anomalous spin transport in a two-channel-Kondo quantum dot device
Prashant Sharma
We study the response of a two-channel Kondo quantum dot device proposed by Y. Oreg and D. Goldhaber-Gordon [Phys. Rev. Lett. {\bf 90}, 136602 (2003)] to a spin-bias applied across…
Electron correlations in metal nanoparticles with spin-orbit scattering
Denis A. Gorokhov, Piet W. Brouwer
The combined effect of electron-electron interactions and spin-orbit scattering in metal nanoparticles can be studied by measuring splitting of electron levels in magnetic field ($…
Electron-Phonon Scattering in Metallic Single-Walled Carbon Nanotubes
Ji-Yong Park, Sami Rosenblatt, Yuval Yaish +6
Electron scattering rates in metallic single-walled carbon nanotubes are studied using an atomic force microscope as an electrical probe. From the scaling of the resistance of the…
On the scaling approach to electron-electron interactions in a chaotic quantum dot
Shaffique Adam, Piet W. Brouwer, Prashant Sharma
A scaling theory is used to study the low energy physics of electron-electron interactions in a double quantum dot. We show that the fact that electrons are delocalized over two qu…
Ultrasharp Crossover from Quantum to Classical Decay in a Quantum Dot Flanked by a Double-Barrier Tunneling Structure
Denis A. Gorokhov, Rava A. da Silveira
The decay of metastable states is dominated by quantum tunneling at low temperatures and by thermal activation at high temperatures. The escape rate of a particle out of a square w…
Tunable Magnetic Relaxation In Magnetic Nanoparticles
Xavier Waintal, Piet W. Brouwer
We investigate the magnetization dynamics of a conducting magnetic nanoparticle weakly coupled to source and drain electrodes, under the assumption that all relaxation comes from e…
Fluctuations of g-factors in metal nanoparticles: Effects of electron-electron interaction and spin-orbit scattering
Denis A. Gorokhov, Piet W. Brouwer
We investigate the combined effect of spin-orbit scattering and electron-electron interactions on the probability distribution of -factors of metal nanoparticles. Using random m…
Mesoscopic effects in adiabatic spin pumping
Prashant Sharma, Piet W. Brouwer
We show that temporal shape modulations (pumping) of a quantum dot in the presence of spin-orbital coupling lead to a finite dc spin current. Depending on the strength of the spin-…
Electrical Nanoprobing of Semiconducting Carbon Nanotubes using an Atomic Force Microscope
Y. Yaish, J. -Y. Park, S. Rosenblatt +3
We use an Atomic Force Microscope (AFM) tip to locally probe the electronic properties of semiconducting carbon nanotube transistors. A gold-coated AFM tip serves as a voltage or c…
Weak localization and conductance fluctuations in a quantum dot with parallel magnetic field and spin-orbit scattering
Jan-Hein Cremers, Piet W. Brouwer, Vladimir I. Falko
In the presence of both spin-orbit scattering and a magnetic field the conductance of a chaotic GaAs quantum dot displays quite a rich behavior. Using a Hamiltonian derived by Alei…
Current-induced transverse spin wave instability in a thin nanomagnet
M. L. Polianski, P. W. Brouwer
We show that an unpolarized electric current incident perpendicular to the plane of a thin ferromagnet can excite a spin-wave instability transverse to the current direction if sou…
Vibrational sidebands and dissipative tunneling in molecular transistors
Stephan Braig, Karsten Flensberg
Transport through molecular devices with strong coupling to a single vibrational mode is considered in the case where the vibration is damped by coupling to the environment. We foc…
Conductance Peak Height Correlations for a Coulomb-Blockaded Quantum Dot in a Weak Magnetic Field
Stephan Braig, Shaffique Adam, Piet W. Brouwer
We consider statistical correlations between the heights of conductance peaks corresponding to two different levels in a Coulomb-blockaded quantum dot. Correlations exist for two p…
Tunneling broadening of vibrational sidebands in molecular transistors
Karsten Flensberg
Transport through molecular quantum dots coupled to a single vibration mode is studied in the case with strong coupling to the leads. We use an expansion in the correlation between…
Crossover from weak localization to weak antilocalization in a disordered microbridge
M. G. A. Crawford, P. W. Brouwer, C. W. J. Beenakker
We calculate the weak localization correction in the double crossover to broken time-reversal and spin-rotational symmetry for a disordered microbridge or a short disordered wire u…
