Hole spin relaxation in -type GaAs quantum wires
C. Lü, U. Zülicke, M. W. Wu
We investigate the spin relaxation of -type GaAs quantum wires by numerically solving the fully microscopic kinetic spin Bloch equations. We find that the quantum-wire size infl…
The unusual temperature dependence of the Eu fluorescence lifetime in CaF crystals
C. K. Duan, A. Mejerink, R. J. Reeves +1
Fluorescence lifetimes of Eu doped in CaF are measured at various temperatures between 4K and 450K. The lifetime increases with between 100K and 300K, in contrast to the…
General calculation of transition rates for rare-earth ions using many-body perturbation theory
Chang-Kui Duan, Michael F. Reid
The transition rates for rare-earth ions in crystals can be calculated with an effective transition operator acting between model and states calculated…
Local Field effects on the radiative lifetime of emitters in surrounding media: virtual- or real-cavity model?
Chang-Kui Duan, Michael F. Reid, Zhongqing Wang
For emitters embedded in media of various refractive indices, different macroscopic or microscopic theoretical models predict different dependencies of the spontaneous emission lif…
Transition from Icosahedral to Decahedral Structure in a Coexisting Solid-Liquid Nickel Cluster
D. Schebarchov, S. C. Hendy
We have used molecular dynamics simulations to construct a microcanonical caloric curve for a 1415-atom Ni icosahedron. Prior to melting the Ni cluster exhibits static solid-liquid…
