Multi-phonon Raman scattering in semiconductor nanocrystals: importance of non-adiabatic transitions
E. P. Pokatilov, S. N. Klimin, V. M. Fomin +2
Multi-phonon Raman scattering in semiconductor nanocrystals is treated taking into account both adiabatic and non-adiabatic phonon-assisted optical transitions. Because phonons of…
Dephasing in a quantum pump
J. N. H. J. Cremers, P. W. Brouwer
We study how dephasing affects the distribution of the dc current pumped through a chaotic quantum dot. We introduce dephasing by the addition of a voltage probe to the quantum dot…
Spin, spin-orbit, and electron-electron interactions in mesoscopic systems
Yuval Oreg, P. W. Brouwer, X. Waintal +1
We review recent theoretical developments about the role of spins, electron-electron interactions, and spin-orbit coupling in metal nanoparticles and semiconductor quantum dots. Fo…
Density of proper delay times in chaotic and integrable quantum billiards
M. G. A. Crawford, P. W. Brouwer
We calculate the density P(τ) of the eigenvalues of the Wigner-Smith time delay matrix for two-dimensional rectangular and circular billiards with one opening. For long times, the…
Solving rate equations for electron tunneling via discrete quantum states
Edgar Bonet, Mandar M. Deshmukh, D. C. Ralph
We consider the form of the current-voltage curves generated when tunneling spectroscopy is used to measure the energies of individual electronic energy levels in nanometer-scale s…
Magnetic Anisotropy Variations and Non-Equilibrium Tunneling in a Cobalt Nanoparticle
M. M. Deshmukh, S. Gueron, E. Bonet +4
We present detailed measurements of the discrete electron-tunneling level spectrum within nanometer-scale cobalt particles as a function of magnetic field and gate voltage, in this…
Renormalization group for network models of Quantum Hall transitions
Denis Bernard, Andre LeClair
We analyze in detail the renormalization group flows which follow from the recently proposed all orders beta functions for the Chalker-Coddington network model. The flows in the ph…
Magnetic exchange interaction induced by a Josephson current
Xavier Waintal, Piet W. Brouwer
We show that a Josephson current flowing through a ferromagnet-normal-metal-ferromagnet trilayer connected to two superconducting electrodes induces an equilibrium exchange interac…
Studies of spin-orbit scattering in noble-metal nanoparticles using energy level tunneling spectroscopy
J. R. Petta, D. C. Ralph
The effects of spin-orbit scattering on discrete electronic energy levels are studied in copper, silver, and gold nanoparticles. Level-to-level fluctuations of the effective -fa…
Equilibrium and non-equilibrium electron tunneling via discrete quantum states
Mandar M. Deshmukh, Edgar Bonet, A. N. Pasupathy +1
Tunneling is measured via the quantum levels of a metal nanoparticle. We analyze quantitatively the resonance energies, widths, and amplitudes, both in the regime where only one st…
Interaction Induced Restoration of Phase Coherence
A. A. Clerk, P. W. Brouwer, V. Ambegaokar
We study the conductance of a quantum T-junction coupled to two electron reservoirs and a quantum dot. In the absence of electron-electron interactions, the conductance is sens…
Weak localization and conductance fluctuations of a chaotic quantum dot with tunable spin-orbit coupling
P. W. Brouwer, J. N. H. J. Cremers, B. I. Halperin
In a two-dimensional quantum dot in a GaAs heterostructure, the spin-orbit scattering rate is substantially reduced below the rate in a bulk two-dimensional electron gas [B.I. Halp…
A Model for Ferromagnetic Nanograins with Discrete Electronic States
Silvia Kleff, Jan von Delft, Mandar M. Deshmukh +1
We propose a simple phenomenological model for an ultrasmall ferromagnetic grain, formulated in terms of the grain's discrete energy levels. We compare the model's predictions with…
Conductance Fluctuations of Open Quantum Dots under Microwave Radiation
Maxim G. Vavilov, Igor L. Aleiner
We develop a time dependent random matrix theory describing the influence of a time-dependent perturbation on mesoscopic conductance fluctuations in open quantum dots. The effect o…
Quantum Effects in Coulomb Blockade
I. L. Aleiner, P. W. Brouwer, L. I. Glazman
We review the quantum interference effects in a system of interacting electrons confined to a quantum dot. The review starts with a description of an isolated quantum dot. We discu…
Pumped current and voltage for an adiabatic quantum pump
M. L. Polianski, P. W. Brouwer
We consider adiabatic pumping of electrons through a quantum dot. There are two ways to operate the pump: to create a dc current or to create a dc voltage . We…
Spectroscopy of discrete energy levels in ultrasmall metallic grains
Jan von Delft, D. C. Ralph
We review recent experimental and theoretical work on ultrasmall metallic grains, i.e. grains sufficiently small that the conduction electron energy spectrum becomes discrete. The…
