Interaction correction to the conductance of a ballistic conductor
Piet W. Brouwer, Joern N. Kupferschmidt
In disordered metals, electron-electron interactions are the origin of a small correction to the conductivity, the "Altshuler-Aronov correction". Here we investigate the Altshuler-…
Effect of Coulomb interaction on current noise in open quantum dots
G. Catelani, M. G. Vavilov
We analyze the effect of Coulomb interaction on the noise of electric current through an open quantum dot. We demonstrate that the ensemble average value of the noise power acquire…
High sensitivity cantilevers for measuring persistent currents in normal metal rings
Ania C. Bleszynski Jayich, Will E. Shanks, Rob Ilic +1
We propose a new approach to measuring persistent currents in normal metal rings. By integrating micron-scale metal rings into sensitive micromechanical cantilevers and using the c…
Graphene Terahertz Plasmon Oscillators
Farhan Rana
In this paper we propose and discuss coherent terahertz sources based on charge density wave (plasmon) amplification in two dimensional graphene. The coupling of the plasmons to in…
Interaction-Induced Strong Localization in Quantum Dots
A. D. Guclu, A. Ghosal, C. J. Umrigar +1
We argue that Coulomb blockade phenomena are a useful probe of the cross-over to strong correlation in quantum dots. Through calculations at low density using variational and diffu…
Demonstration of one-parameter scaling at the Dirac point in graphene
J. H. Bardarson, J. Tworzydło, P. W. Brouwer +1
We numerically calculate the conductivity of an undoped graphene sheet (size ) in the limit of vanishingly small lattice constant. We demonstrate one-parameter scaling for r…
Semiclassical theory of the Ehrenfest-time dependence of quantum transport
Piet W. Brouwer
In ballistic conductors, there is a low-time threshold for the appearance of quantum effects in transport coefficients. This low-time threshold is the Ehrenfest time. Most previous…
Universal parametric correlations in the classical limit of quantum transport
Piet W. Brouwer, Saar Rahav
Quantum corrections to transport through a chaotic ballistic cavity are known to be universal. The universality not only applies to the magnitude of quantum corrections, but also t…
Electron-Hole Generation and Recombination Rates for Coulomb Scattering in Graphene
Farhan Rana
We calculate electron-hole generation and recombination rates for Coulomb scattering (Auger recombination and impact ionization) in Graphene. The conduction and valence band disper…
Large-amplitude coherent spin waves exited by spin-polarized current in nanoscale spin valves
I. N. Krivorotov, D. V. Berkov, N. L. Gorn +4
We present spectral measurements of spin-wave excitations driven by direct spinpolarized current in the free layer of nanoscale Ir20Mn80/Ni80Fe20/Cu/Ni80Fe20 spin valves. The measu…
A theoretical model for single molecule incoherent scanning tunneling spectroscopy
Hassan Raza
Single molecule scanning tunneling spectroscopy (STS), with dephasing due to elastic and inelastic scattering, is of some current interest. Motivated by this, we report an extended…
Incipient Wigner Localization in Circular Quantum Dots
Amit Ghosal, A. D. Guclu, C. J. Umrigar +2
We study the development of electron-electron correlations in circular quantum dots as the density is decreased. We consider a wide range of both electron number, N<=20, and electr…
Quantum Theory of Cavity-Assisted Sideband Cooling of Mechanical Motion
Florian Marquardt, Joe P. Chen, A. A. Clerk +1
We present a fully quantum theory describing the cooling of a cantilever coupled via radiation pressure to an illuminated optical cavity. Applying the quantum noise approach to the…
