Effect of detuning on the phonon induced dephasing of optically driven InGaAs/GaAs quantum dots
A. J. Ramsay, T. M. Godden, S. J. Boyle +6
Recently, longitudinal acoustic phonons have been identified as the main source of the intensity damping observed in Rabi rotation measurements of the ground-state exciton of a sin…
Direct measurement of the hole-nuclear spin interaction in single quantum dots
E. A. Chekhovich, A. B. Krysa, M. S. Skolnick +1
We use photoluminescence spectroscopy of ''bright'' and ''dark'' exciton states in single InP/GaInP quantum dots to measure hyperfine interaction of the valence band hole with nucl…
Alignment of nuclear spins in single quantum dots using unpolarized light
E. A. Chekhovich, A. B. Krysa, M. S. Skolnick +1
We report optical pumping of neutral quantum dots leading to nuclear spin alignment with direction insensitive to polarization and wavelength of light. Measurements of photolumines…
Design and Characterization of a Field-Switchable Nanomagnetic Atom Mirror
T. J. Hayward, A. D. West, K. J. Weatherill +9
We present a design for a switchable nanomagnetic atom mirror formed by an array of 180° domain walls confined within Ni80Fe20 planar nanowires. A simple analytical model is develo…
Microcavity quantum-dot systems for non-equilibrium Bose-Einstein condensation
I. M. Piper, P. R. Eastham, M. Ediger +5
We review the practical conditions required to achieve a non-equilibrium BEC driven by quantum dynamics in a system comprising a microcavity field mode and a distribution of locali…
Modelling Multi Quantum Well Solar Cell Efficiency
James P. Connolly, Jenny Nelson, Ian Ballard +5
The spectral response of quantum well solar cells (QWSCs) is well understood. We describe work on QWSC dark current theory which combined with SR theory yields a system efficiency.…
