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…
Disorder-induced critical phenomena--new universality classes in Anderson localization
P. W. Brouwer, A. Furusaki, C. Mudry +1
The Anderson metal-insulator transition is a continuous phase transition driven by disorder. It remains a challenging problem to theoretically determine universal critical properti…
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…
