Valence state manipulation of single Fe impurities in GaAs by STM
J. Bocquel, V. R. Kortan, R. P. Campion +3
The incorporation of Fe in GaAs was studied by cross-sectional scanning tunneling microscopy (X-STM). The observed local electronic contrast of a single Fe atom is found to depend…
Strong-field interactions between a nanomagnet and a photonic cavity
Öney O. Soykal, M. E. Flatté
We analyze the interaction of a nanomagnet with a single photonic mode of a microcavity in a fully quantum-mechanical treatment and find that exceptionally large quantum-coherent m…
Predicted Ultrafast Single Qubit Operations in Semiconductor Quantum Dots
C. E. Pryor, M. E. Flatté
Several recently proposed implementations of scalable quantum computation rely on the ability to manipulate the spin polarization of individual electrons in semiconductors. The mos…
Coherent Exciton Lasing in ZnSe/ZnCdSe Quantum Wells?
M. E. Flatte', E. Runge, H. Ehrenreich
A new mechanism for exciton lasing in ZnSe/ZnCdSe quantum wells is proposed. Lasing, occurring below the lowest exciton line, may be associated with a BCS-like condensed (coherent)…
Kohn Anomalies in Superconductors
M. E. Flatte'
I present the detailed behavior of phonon dispersion curves near momenta which span the electronic Fermi sea in a superconductor. I demonstrate that an anomaly, similar to the meta…
Image of the Energy Gap Anisotropy in the Vibrational Spectum of a High Temperature Superconductor
Michael E. Flatte
We present a new method of determining the anisotropy of the gap function in layered high-Tc superconductors. Careful inelastic neutron scattering measurements at low temperature o…
