Tuning the Kondo effect with a mechanically controllable break junction

J. J. Parks, A. R. Champagne, G. R. Hutchison +3

We study electron transport through C60 molecules in the Kondo regime using a mechanically controllable break junction. By varying the electrode spacing, we are able to change both…

Non-equilibrium charge noise and dephasing from a spin-incoherent Luttinger liquid

Gregory A. Fiete, Markus Kindermann

We theoretically investigate the charge noise and dephasing in a metallic device in close proximity to a spin incoherent Luttinger liquid with a small but finite current. The frequ…

Semiclassical theory of a quantum pump

Saar Rahav, Piet W. Brouwer

In a quantum charge pump, the periodic variation of two parameters that affect the phase of the electronic wavefunction causes the flow of a direct current. The operating mechanism…

Theory of the spin-torque-driven ferromagnetic resonance in a ferromagnet/normal-metal/ferromagnet structure

Joern N. Kupferschmidt, Shaffique Adam, Piet W. Brouwer

We present a theoretical analysis of current driven ferromagnetic resonance in a ferromagnet/normal-metal/ferromagnet tri-layer. This method of driving ferromagnetic resonance was…

Towards a semiclassical justification of the `effective random matrix theory' for transport through ballistic chaotic quantum dots

Piet W. Brouwer, Saar Rahav

The scattering matrix S of a ballistic chaotic cavity is the direct sum of a `classical' and a `quantum' part, which describe the scattering of channels with typical dwell time sma…

Multiple crossovers in interacting quantum wires

M. Kindermann, P. W. Brouwer

We study tunneling of electrons into and between interacting wires in the spin-incoherent regime subject to a magnetic field. The tunneling currents follow power laws of the applie…

Fragmentation of Bose-Einstein Condensates

Erich J. Mueller, Tin-Lun Ho, Masahito Ueda +1

We present the theory of bosonic systems with multiple condensates, unifying disparate models which are found in the literature, and discuss how degeneracies, interactions, and sym…

Interplay of Ehrenfest time and dephasing time in ballistic conductors

Alexander Altland, Piet W. Brouwer, Chushun Tian

Quantum interference corrections in ballistic conductors require a minimal time: the Ehrenfest time. In this letter, we investigate the fate of the interference corrections to quan…

Interference as a Probe of Spin Incoherence in Strongly Interacting Quantum Wires

M. Kindermann, P. W. Brouwer, A. J. Millis

We show that interference experiments can be used to identify the spin-incoherent regime of strongly interacting one-dimensional conductors. Two qualitative signatures of spin-inco…

Signatures of Molecular Magnetism in Single-Molecule Transport Spectroscopy

Moon-Ho Jo, Jacob E. Grose, Kanhayalal Baheti +7

Single-molecule transistors provide a unique experimental tool to investigate the coupling between charge transport and the molecular degrees of freedom in individual molecules. On…

Anisotropic magnetoresistance and anisotropic tunneling magnetoresistance due to quantum interference in ferromagnetic metal break junctions

Kirill I. Bolotin, Ferdinand Kuemmeth, D. C. Ralph

We measure the low-temperature resistance of permalloy break junctions as a function of contact size and the magnetic field angle, in applied fields large enough to saturate the ma…

Correlation Induced Inhomogeneity in Circular Quantum Dots

Amit Ghosal, A. D. Guclu, C. J. Umrigar +2

Properties of the "electron gas" - in which conduction electrons interact by means of Coulomb forces but ionic potentials are neglected - change dramatically depending on the balan…
