Coulomb Blockade Peak Spacings: Interplay of Spin and Dot-Lead Coupling
Serguei Vorojtsov, Harold U. Baranger
For Coulomb blockade peaks in the linear conductance of a quantum dot, we study the correction to the spacing between the peaks due to dot-lead coupling. This coupling can affect m…
Models of Electrodes and Contacts in Molecular Electronics
San-Huang Ke, Harold U. Baranger, Weitao Yang
Bridging the difference in atomic structure between experiments and theoretical calculations and exploring quantum confinement effects in thin electrodes (leads) are both important…
Fermi Edge Singularities in the Mesoscopic Regime: I. Anderson Orthogonality Catastrophe
Martina Hentschel, Denis Ullmo, Harold U. Baranger
For generic mesoscopic systems like quantum dots or nanoparticles, we study the Anderson orthogonality catastrophe (AOC) and Fermi edge singularities in photoabsorption spectra in…
Phonon Decoherence of a Double Quantum Dot Charge Qubit
Serguei Vorojtsov, Eduardo R. Mucciolo, Harold U. Baranger
We study decoherence of a quantum dot charge qubit due to coupling to piezoelectric acoustic phonons in the Born-Markov approximation. After including appropriate form factors, we…
Interactions and Broken Time-Reversal Symmetry in Chaotic Quantum Dots
Denis Ullmo, Hong Jiang, Weitao Yang +1
When treating interactions in quantum dots within a RPA-like approach, time-reversal symmetry plays an important role as higher-order terms -- the Cooper series -- need to be inclu…
Cluster Algorithms for Quantum Impurity Models and Mesoscopic Kondo Physics
Jaebeom Yoo, Shailesh Chandrasekharan, Ribhu K. Kaul +2
Nanoscale physics and dynamical mean field theory have both generated increased interest in complex quantum impurity problems and so have focused attention on the need for flexible…
