Scalable Quantum Computing with "Enhancement" Quantum Dots
Y. B. Lyanda-Geller, M. J. Yang, C. H. Yang
We propose a novel scheme of solid state realization of a quantum computer based on single spin "enhancement mode" quantum dots as building blocks. In the enhancement quantum dots,…
Asymmetric exchange between electron spins in coupled semiconductor quantum dots
Ş. C. Bădescu, Y. Lyanda-Geller, T. L. Reinecke
We obtain a microscopic description of the interaction between electron spins in bulk semiconductors and in pairs of semiconductor quantum dots. Treating the k.p band mixing and th…
Magnetotransport in manganites and the role of quantal phases I: Theory
Y. Lyanda-Geller, P. M. Goldbart, S. H. Chun +1
A microscopic picture of charge transport in manganites is developed, with particular attention being paid to the neighborhood of the ferromagnet-to- paramagnet phase transition. T…
Mesoscopic phenomena in Bose-Einstein systems: Persistent currents, population oscillations and quantal phases
Yuli Lyanda-Geller, Paul M. Goldbart
Mesoscopic phenomena - including population oscillations and persistent currents driven by quantal phases - are explored theoretically in the context of multiply-connected Bose-Ein…
