Microscopic model of critical current noise in Josephson-junction qubits: Subgap resonances and Andreev bound states
Rogerio de Sousa, K. Birgitta Whaley, Theresa Hecht +2
We propose a microscopic model of critical current noise in Josephson-junctions based on individual trapping-centers in the tunnel barrier hybridized with electrons in the supercon…
Comment on "Ferroelectrically Induced Weak Ferromagnetism by Design", C. Fennie, PRL 100, 167203 (2008)
Rogerio de Sousa, Joel E. Moore
The question of how ferroelectric polarization is coupled to magnetism in magnetoelectric multiferroics, in which both types of order are simultaneously present, is of considerable…
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…
Universal Scaling of Hyperfine-Induced Electron Spin Echo Decay
Neil Shenvi, Rogerio de Sousa, K. Birgitta Whaley
The decoherence of a localized electron spin in a lattice of nuclear spins is an important problem for potential solid-state implementations of a quantum computer. We demonstrate t…
Qubit coherence control in a nuclear spin bath
Rogerio de Sousa, Neil Shenvi, K. Birgitta Whaley
Coherent dynamics of localized spins in semiconductors is limited by spectral diffusion arising from dipolar fluctuation of lattice nuclear spins. Here we extend the semiclassical…
