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…
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…
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…
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…
