Angewandte Chemie (International ed. in English)

Böhnke J, Braunschweig H, Dellermann T, Ewing WC, Hammond K, Jimenez-Halla JO, Kramer T, Mies J.
PMID: 26427026
Angew Chem Int Ed Engl. 2015 Nov 09;54(46):13801-5. doi: 10.1002/anie.201506368. Epub 2015 Oct 01.

A new compound with the formula L-B2-L wherein the stabilizing ligand (L) is 1,3-bis[diisopropylphenyl]-4,5-dihydroimidazol-2-ylidene (SIDip) has been synthesized, isolated, and characterized. The π-acidity of the SIDip ligand, intermediate between the relatively non-acidic IDip (1,3-bis[diisopropylphenyl]imidazol-2-ylidene) ligand and the much more...

Optically induced entanglement of excitons in a single quantum Dot.

Science (New York, N.Y.)

Chen G, Bonadeo NH, Steel DG, Gammon D, Katzer DS, Park D, Sham LJ.
PMID: 10988065
Science. 2000 Sep 15;289(5486):1906-9. doi: 10.1126/science.289.5486.1906.

Optically induced entanglement is identified by the spectrum of the phase-sensitive homodyne-detected coherent nonlinear optical response in a single gallium arsenide quantum dot. The electron-hole entanglement involves two magneto-excitonic states differing in transition energy and polarization. The strong coupling...

Manipulation of the spin memory of electrons in n-GaAs.

Physical review letters

Dzhioev RI, Korenev VL, Merkulov IA, Zakharchenya BP, Gammon D, Efros AL, Katzer DS.
PMID: 12097110
Phys Rev Lett. 2002 Jun 24;88(25):256801. doi: 10.1103/PhysRevLett.88.256801. Epub 2002 Jun 05.

We report on the optical manipulation of the electron spin relaxation time in a GaAs-based heterostructure. Experimental and theoretical study shows that the average electron spin relaxes through hyperfine interaction with the lattice nuclei, and that the rate can...

Biexciton quantum coherence in a single quantum dot.

Physical review letters

Phys Rev Lett. 2002 Mar 18;88(11):117901. doi: 10.1103/PhysRevLett.88.117901. Epub 2002 Mar 05.

Nondegenerate (two-wavelength) two-photon absorption using coherent optical fields is used to show that there are two different quantum mechanical pathways leading to formation of the biexciton in a single quantum dot. Of specific importance to quantum information applications is...

An all-optical quantum gate in a semiconductor quantum dot.

Science. 2003 Aug 08;301(5634):809-11. doi: 10.1126/science.1083800.

We report coherent optical control of a biexciton (two electron-hole pairs), confined in a single quantum dot, that shows coherent oscillations similar to the excited-state Rabi flopping in an isolated atom. The pulse control of the biexciton dynamics, combined...

An asymmetric pair of coupled InAs quantum dots is tuned into resonance by applying an electric field so that a single hole forms a coherent molecular wave function. The optical spectrum shows a rich pattern of level anticrossings and...

A study to ascertain the effect of structured student tutorial support on student stress, self-esteem and coping.

The overall aim of this intervention study was to investigate, and measure quantitatively, the psychological effects of structured student tutorial support, on undergraduate students' level of stress, self-esteem and cognitive coping. A quantitative research approach was adopted using a...
