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…
Interaction Effects in the Mesoscopic Regime: A Quantum Monte Carlo Study of Irregular Quantum Dots
Amit Ghosal, C. J. Umrigar, Hong Jiang +2
We address the issue of accurately treating interaction effects in the mesoscopic regime by investigating the ground state properties of isolated irregular quantum dots. Quantum Mo…
Mesoscopic Kondo Problem
Ribhu K. Kaul, Denis Ullmo, Shailesh Chandrasekharan +1
We study the effect of mesoscopic fluctuations on a magnetic impurity coupled to a spatially confined electron gas with a temperature in the mesoscopic range (i.e. between the mean…
Statistics of Wave Functions in Disordered Systems with Applications to Coulomb Blockade Peak Spacing
Mike Miller, Denis Ullmo, Harold U. Baranger
Despite considerable work on the energy-level and wavefunction statistics of disordered quantum systems, numerical studies of those statistics relevant for electron-electron intera…
Scrambling and Gate Effects in Realistic Quantum Dots
Hong Jiang, Denis Ullmo, Weitao Yang +1
We evaluate the magnitude of two important mesoscopic effects using a realistic model of typical quantum dots. ``Scrambling'' and ``gate effect'' are defined as the change in the s…
