Frequency-dependent spontaneous emission rate from CdSe and CdTe nanocrystals: influence of dark states
A. F. van Driel, G. Allan, C. Delerue +3
We studied the rate of spontaneous emission from colloidal CdSe and CdTe nanocrystals at room temperature. The decay rate, obtained from luminescence decay curves, increases with t…
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…
Spin-excitations of the quantum Hall ferromagnet of composite fermions
R. L. Doretto, M. O. Goerbig, P. Lederer +2
The spin-excitations of a fractional quantum Hall system are evaluated within a bosonization approach. In a first step, we generalize Murthy and Shankar's Hamiltonian theory of the…
Accelerated dynamics with the dynamical activation-relaxation technique
G. T. Barkema, Normand Mousseau
The dynamics of many atomic systems is controlled by activated events taking place on a time scale which is long compared to that associated with thermal vibrations. This often pla…
Efficient sampling in complex materials at finite temperature: the thermodynamically-weighted activation-relaxation technique
Normand Mousseau, G. T. Barkema
We present an accelerated algorithm that samples correctly the thermodynamic ensemble in complex systems where the dynamics is controlled by activation barriers. The efficiency of…
