Quantum simulation of multiple-exciton generation in a nanocrystal by a single photon
Wayne M. Witzel, Andrew Shabaev, C. Stephen Hellberg +2
We have shown theoretically that efficient multiple exciton generation (MEG) by a single photon can be observed in small nanocrystals (NCs). Our quantum simulations that include hu…

Multiple-pulse coherence enhancement of solid state spin qubits
W. M. Witzel, S. Das Sarma
We describe how the spin coherence time of a localized electron spin in solids, i.e. a solid state spin qubit, can be prolonged by applying designed electron spin resonance pulse s…

Line Broadening and Decoherence of Electron Spins in Phosphorus-Doped Silicon Due to Environmental 29^Si Nuclear Spins
Eisuke Abe, Akira Fujimoto, Junichi Isoya +2
Phosphorus-doped silicon single crystals with 0.19 % <= f <= 99.2 %, where f is the concentration of 29^Si isotopes, are measured at 8 K using a pulsed electron spin resonance tech…
