Quantum dot-cavity strong-coupling regime measured through coherent reflection spectroscopy in a very high-Q micropillar
Quantum dot-cavity strong-coupling regime coherent reflection spectroscopy high-Q micropillar
2010/11/18
We report on the coherent reflection spectroscopy of a high-quality factor micropillar, in the strong coupling regime with a single InGaAs annealed quantum dot. The absolute reflectivity measurement i...
Direct observation of dynamic surface acoustic wave controlled carrier injection into single quantum posts using phase-resolved optical spectroscopy
quantum dot quantum post surface acoustic wave carrier injection
2010/11/19
A versatile stroboscopic technique based on active phase-locking of a surface acoustic wave to picosecond laser pulses is used to monitor dynamic acoustoelectric e ects.Time-integrated multi-channel d...

Entanglement spectrum random-singlet quantum critical points
2010/10/22
The entanglement spectrum, i.e., the full distribution of Schmidt eigenvalues of the reduced
density matrix, contains more information than the conventional entanglement entropy and has been studied ...
High Overtones of Dirac Perturbations of a Schwarzschild Black Hole and the Area Spectrum of Quantum Black Holes
Dirac Perturbations a Schwarzschild Black Hole the Area Spectrum Quantum Black Holes
2010/10/18
We find high overtones of the Dirac quasi-normal (QN) spectrum of a Schwarzschild black hole (Sbh), by Leaver’s method. At high overtones, the spacing of the imaginary part of the QN spectrum is equid...
Quantum Correlations in Inflationary Spectra and Violation of Bell Inequalities
Quantum Correlations Inflationary Spectra Violation of Bell Inequalities
2010/10/18
In spite of the macroscopic character of the fluctuation amplitudes, we show that the standard inflationary distribution of primordial density fluctuations still exhibits inherently quantum mechanical...

Energy Spectra GaAs/AlxGa1-xAs Quantum Dots
2010/4/19
The energy expressions for QD presented in high- and low-magnetic fields are calculated. An interpolation formula between the energies of the quantum dot in both limits is proposed. The formula is imp...
