Rate equations for Coulomb blockade with ferromagnetic leads
Stephan Braig, Piet W. Brouwer
We present a density-matrix rate-equation approach to sequential tunneling through a metal particle weakly coupled to ferromagnetic leads. The density-matrix description is able to…
Mesoscopic bound on anisotropy in itinerant ferromagnets
Piet W. Brouwer, Denis A. Gorokhov
We calculate the anisotropy energy of a single-domain ferromagnetic particle in which the only source of anisotropy is the presence of non-magnetic impurities. We find that such an…
Time-Resolved Intraband Relaxation of Strongly-Confined Electrons and Holes in Colloidal PbSe Nanocrystals
Jeffrey M. Harbold, Frank W. Wise, Hui Du +3
The relaxation of strongly-confined electrons and holes between 1P and 1S levels in colloidal PbSe nanocrystals has been time-resolved using femtosecond transient absorption spectr…
Modelling a suspended nanotube oscillator
H. Ustunel, D. Roundy, T. A. Arias
We present a general study of oscillations in suspended one-dimensional elastic systems clamped at each end, exploring a wide range of slack (excess length) and downward external f…
Interaction Effects in the Mesoscopic Regime: A Quantum Monte Carlo Study of Irregular Quantum Dots
Amit Ghosal, C. J. Umrigar, Hong Jiang +2
We address the issue of accurately treating interaction effects in the mesoscopic regime by investigating the ground state properties of isolated irregular quantum dots. Quantum Mo…
Electronic shell effects and the stability of alkali nanowires
D. F. Urban, J. Bürki, A. I. Yanson +4
Experimental conductance histograms for Na nanowires are analyzed in detail and compared to recent theoretical results on the stability of cylindrical and elliptical nanowires, usi…
Wigner Crystallization in inhomogeneous one dimensional wires
Erich J. Mueller
We explore the theory of electrons confined by one dimensional power law potentials. We calculate the density profile in the high density electron gas, the low density Wigner cryst…
A tunable carbon nanotube electromechanical oscillator
Vera Sazonova, Yuval Yaish, Hande Ustunel +3
Nanoelectromechanical systems (NEMs) hold promise for a number of scientific and technological applications. In particular, NEMs oscillators have been proposed for use in ultrasens…
Mechanically-adjustable and electrically-gated single-molecule transistors
A. R. Champagne, A. N. Pasupathy, D. C. Ralph
We demonstrate a device geometry for single-molecule electronics experiments that combines both the ability to adjust the spacing between the electrodes mechanically and the abilit…
Weak Coulomb blockade effect in quantum dots
Piet W. Brouwer, Austen Lamacraft, Karsten Flensberg
We develop the general non-equilibrium theory of transport through a quantum dot, including Coulomb Blockade effects via a 1/N expansion, where N is the number of scattering channe…
Measurement of long-range wavefunction correlations in an open microwave billiard
Y. -H. Kim, U. Kuhl, H. -J. Stöckmann +1
We investigate the statistical properties of wavefunctions in an open chaotic cavity. When the number of channels in the openings of the billiard is increased by varying the freque…
Exponential sensitivity to dephasing of electrical conduction through a quantum dot
J. Tworzydlo, A. Tajic, H. Schomerus +2
According to random-matrix theory, interference effects in the conductance of a ballistic chaotic quantum dot should vanish when the dephasing time b…
Density profile of a harmonically trapped ideal Fermi gas in arbitrary dimension
Erich J. Mueller
Closed form analytic expressions are derived for the density profile of a harmonically trapped noninteracting Fermi gas in dimensions. Shell structure effects are included to l…
Spin-dependent transport in molecular tunnel junctions
J. R. Petta, S. K. Slater, D. C. Ralph
We present measurements of magnetic tunnel junctions made using a self-assembled-monolayer molecular barrier. Ni/octanethiol/Ni samples were fabricated in a nanopore geometry. The…
Measuring electron orbital magnetic moments in carbon nanotubes
E. D. Minot, Yuval Yaish, Vera Sazonova +1
The remarkable transport properties of carbon nanotubes (NTs) are determined by their unique electronic structure (1). The electronic states of a NT form one-dimensional electron a…
Comment on "Magnetic response of Disordered Metallic Rings: Large Contributions of Far Levels"
U. Eckern, P. Schwab, V. Ambegaokar
Comment on cond-mat/0205390; PRL 90, 026805 (2003)
Dissipative tunneling and orthogonality catastrophe in molecular transistors
Stephan Braig, Karsten Flensberg
Transport through molecular devices with weak tunnel coupling to the leads but with strong coupling to a single vibrational mode is considered in the case where the vibration is da…
