Decoherence by Correlated Noise and Quantum Error Correction
E. Novais, Harold U. Baranger
We study the decoherence of a quantum computer in an environment which is inherently correlated in time and space. We first derive the nonunitary time evolution of the computer and…
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…
