  1. 11. Designing an Experiment to Investigate Slow Light Effects in Whispering Gallery Mode Resonators

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Karolina Dorozynska; [2015]
    Keywords : Slow light; Whispering Gallery Mode Resonator; WGMR; Atomic physics; Physics and Astronomy;

    Abstract : Slow light and Whispering Gallery Mode Resonators are two interesting and useful fields with applications in optical sensing and laser stabilisation among others. Slow light can lead to long interaction times which are useful in light-matter interactions such as sensitive non-linear optics. READ MORE

  3. 12. Saturation Intensity of Rare Earth Ions Doped Crystals

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Author : Martynas Solovejus; [2014]
    Keywords : saturation intensity; spectral broadening; spectral effects; rare earths; rare-earths; cerium; Ce; Ce:YSO; Pr:YSO; RE:YSO; quantum information; quantum computing; Physics and Astronomy;

    Abstract : The thesis is primarily concerned with rare earth ions doped into yttrium ortho silicate crystals, RE:YSO. It is considered to be an ambitious platform for the development of quantum computing schemes. One such scheme requires the detection of single cerium ions. READ MORE

  4. 13. Dynamics of the η' meson at finite temperature

    University essay from Uppsala universitet/Kärnfysik

    Author : Elisabetta Perotti; [2014]
    Keywords : effective field theory; chiral perturbation theory; resonance chiral theory; large Nc limit; chiral anomaly;

    Abstract : At the present time it is unknown how the U(1)A anomaly of Quantum Chromodynamics behaves at high temperatures. We therefore want to look for thermal changes of the effects of the anomaly. READ MORE

  5. 14. Synthesis and characterisation of ZnO nanoparticles.An experimental investigation of some of their size dependent quantum effects

    University essay from Institutionen för materialkemi

    Author : T. Jesper Jacobsson; [2010]
    Keywords : ZnO; nanoparticles; quantum dots; Sol-gel; Time resolved UV-Vis spectroscopy; fluorescence; Raman; Phonon spectrum; Synthesis; XRD;

    Abstract : ZnO nanoparticles in the size range 2.5–7 nm have been synthesised by a wet chemical method where ZnO particles were grown in basic zinc acetate solution. The optical band gap increases when the size of the particles decreases. READ MORE

  6. 15. Low-temperature synthesis of CdS nanocrystals in aliphatic alcohols

    University essay from Institutionen för materialkemi

    Author : Lina Martinsson; [2010]
    Keywords : Low temperature; CdS nanocrystals; One-pot;

    Abstract : In this report a novel low temperature synthesis approach of CdS nanocrystals is described starting from well known precursors, Cd(SA) and TOP-S, in a ligand system of aliphatic long chain alcohols. A one-pot synthesis approach is applied using a laboratory microwave heating source. READ MORE
