Loss of Pi-Junction Behaviour in an Interacting Impurity Josephson Junction

Aashish A. Clerk, Vinay Ambegaokar

Using a generalization of the non-crossing approximation which incorporates Andreev reflection, we study the properties of an infinite-U Anderson impurity coupled to two supercondu…

gl(N|N) Super-Current Algebras for Disordered Dirac Fermions in Two Dimensions

S. Guruswamy, A. LeClair, A. W. W. Ludwig

We consider the non-hermitian 2D Dirac Hamiltonian with (A): real random mass, imaginary scalar potential and imaginary gauge field potentials, and (B) arbitrary complex random pot…

Current-driven Magnetization Reversal and Spin Wave Excitations in Co/Cu/Co Pillars

J. A. Katine, F. J. Albert, R. A. Buhrman +2

Using thin film pillars ~100 nm in diameter, containing two ferromagnetic Co layers of different thicknesses separated by a paramagnetic Cu spacer, we examine effects of torques du…

Topological Phase Diagram of a Two-Subband Electron System

X. Y. Lee, H. W. Jiang, W. J. Schaff

We present a phase diagram for a two-dimensional electron system with two populated subbands. Using a gated GaAs/AlGaAs single quantum well, we have mapped out the phases of variou…

Gauge Invariance and the Critical Properties of Quantum Hall Plateaux Transitions

Andre' LeClair

A model consisting of a single massless scalar field with a topological coupling to a pure gauge field is defined and studied. It possesses an SL(2,Z) symmetry as a consequence of…

On the Relevance of Disorder for Dirac Fermions with Imaginary Vector Potential

Andre' LeClair

We consider the effects of disorder in a Dirac-like Hamiltonian. In order to use conformal perturbation theory, we argue that one should consider disorder in an imaginary vector po…

Theory of Dephasing by External Perturbation in Open Quantum Dots

M. G. Vavilov, I. L. Aleiner

We propose a random matrix theory describing the influence of a time dependent external field on the average magnetoresistance of open quantum dots. The effect is taken into accoun…

Effects of Spin-Orbit Interactions on Tunneling via Discrete Energy Levels in Metal Nanoparticles

D. G. Salinas, S. Guéron, D. C. Ralph +2

The presence of spin-orbit scattering within an aluminum nanoparticle affects measurements of the discrete energy levels within the particle by (1) reducing the effective g-factor…

Tunneling Via Individual Electronic States in Ferromagnetic Nanoparticles

S. Gueron, Mandar M. Deshmukh, E. B. Myers +1

We measure electron tunneling via discrete energy levels in ferromagnetic cobalt particles less than 4 nm in diameter, using non-magnetic electrodes. Due to magnetic anisotropy, th…
