Mesoscopic anisotropic magnetoconductance fluctuations in ferromagnets
Shaffique Adam, Markus Kindermann, Saar Rahav +1
The conductance of a ferromagnetic particle depends on the relative orientation of the magnetization with respect to the direction of current flow. This phenomenon is known as "ani…
Ehrenfest time and the coherent backscattering off ballistic cavities
Saar Rahav, Piet W. Brouwer
If the Ehrenfest time tau_E of a ballistic cavity is not negligible in comparison to its dwell time tau_D, the weak localization correction to the cavity's transmission is suppress…
A semiclassical theory of the Ehrenfest-time dependence of quantum transport in ballistic quantum dots
Piet W. Brouwer, Saar Rahav
We present a trajectory-based semiclassical calculation of the Ehrenfest-time dependence of the weak localization correction and the universal conductance fluctuations of a ballist…
Time-Resolved Spin Torque Switching and Enhanced Damping in Py/Cu/Py Spin-Valve Nanopillars
N. C. Emley, I. N. Krivorotov, A. G. F. Garcia +4
We report time-resolved measurements of current-induced reversal of a free magnetic layer in Py/Cu/Py elliptical nanopillars at temperatures T = 4.2 K to 160 K. Comparison of the d…
Spin torque, tunnel-current spin polarization and magnetoresistance in MgO magnetic tunnel junctions
G. D. Fuchs, J. A. Katine, S. I. Kiselev +4
We examine the spin torque (ST) response of magnetic tunnel junctions (MTJs) with ultra-thin MgO tunnel barrier layers to investigate the relationship between the spin-transfer tor…
From ballistic transport to tunneling in electromigrated ferromagnetic breakjunctions
Kirill I. Bolotin, F. Kuemmeth, Abhay N. Pasupathy +1
We fabricate ferromagnetic nanowires with constrictions whose cross section can be reduced gradually from 100 nm to the atomic scale and eventually to the tunneling regime by means…
Current induced transverse spin-wave instability in thin ferromagnets: beyond linear stability analysis
Shaffique Adam, Mikhail L. Polianski, Piet W. Brouwer
A sufficiently large unpolarized current can cause a spin-wave instability in thin nanomagnets with asymmetric contacts. The dynamics beyond the instability is understood in the pe…
Classical limit of transport in quantum kicked maps
Saar Rahav, Piet W. Brouwer
We investigate the behavior of weak localization, conductance fluctuations, and shot noise of a chaotic scatterer in the semiclassical limit. Time resolved numerical results, obtai…
Shot noise free conductance reduction in quantum wires
M. Kindermann, P. W. Brouwer
We show that a shot noise free current at conductance below 2 e^2/h is possible in short interacting quantum wires without spin-polarization. Our calculation is done for two exactl…
The maximum density droplet to lower density droplet transition in quantum dots
A. D. Güçlü, C. J. Umrigar
We show that, Landau level mixing in two-dimensional quantum dot wave functions can be taken into account very effectively by multiplying the exact lowest Landau level wave functio…
Ehrenfest-time dependence of weak localization in open quantum dots
Saar Rahav, Piet W. Brouwer
Semiclassical theory predicts that the weak localization correction to the conductance of a ballistic chaotic cavity is suppressed if the Ehrenfest time exceeds the dwell time in t…
Band Structure, Phonon Scattering and the Ultimate Performance of Single-Walled Carbon Nanotube Transistors
Xinjian Zhou, Ji-Yong Park, Shaoming Huang +2
Semiconducting single-walled carbon nanotubes are studied in the diffusive transport regime. The peak mobility is found to scale with the square of the nanotube diameter and invers…
Nonequilibrium theory of Coulomb blockade in open quantum dots
Piet W. Brouwer, Austen Lamacraft, Karsten Flensberg
We develop a non-equilibrium theory to describe weak Coulomb blockade effects in open quantum dots. Working within the bosonized description of electrons in the point contacts, we…
