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…

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…
