Ohmic and step noise from a single trapping center hybridized with a Fermi sea
Rogerio de Sousa, K. Birgitta Whaley, Frank K. Wilhelm +1
We show that single electron tunneling devices such as the Cooper-pair box or double quantum dot can be sensitive to the zero-point fluctuation of a single trapping center hybridiz…
Thomas-Fermi Theory of the Hyperfine Constants of Endohedral Fullerene Atoms
Joshua Schrier, K. Birgitta Whaley
We present a modified Thomas-Fermi theory that describes the increase of the hyperfine coupling constants of endohedrally enclosed atoms. We use the March boundary conditions corre…
Non-Perturbative Bounds on Hyperfine-Induced Electron Spin Coherence Times
Neil Shenvi, Rogerio de Sousa, K. Birgitta Whaley
We address the decoherence of a localized electron spin in an external magnetic field due to the hyperfine interaction with a lattice of nuclear spins. Using a completely non-pertu…
Electronic transport, structure, and energetics of endohedral Gd@C82 metallofullerenes
Laxmidhar Senapati, Joshua Schrier, K. Birgitta Whaley
Electronic structure and transport properties of the fullerene C and the metallofullerene Gd@C are investigated with density functional theory and the Landauer-Buttik…
Implementing a Quantum Algorithm with Exchange-Coupled Quantum Dots: a Feasibility study
E. Simon Myrgren, K. Birgitta Whaley
We present Monte Carlo wavefunction simulations for quantum computations employing an exchange-coupled array of quantum dots. Employing a combination of experimentally and theoreti…
A Simple Model for Magnetization Ratios in Doped Nanocrystals
Joshua Schrier, K. Birgitta Whaley
Recent experiments on Mn-doped ZnS nanocrystals have shown unusual magnetization properties. We describe a nearest-neighbor Heisenberg exchange model for calculating the magnetizat…
