1. 1. Coherent Plasmon-Plasmon and Plasmon-Exciton Interactions at the Nanoscale

   Författare :Martin Wersäll; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; directional emission; coherent interactions; strong coupling; localized surface plasmon resonances;

   Sammanfattning : Noble metallic nanoparticles which supports localized surface plasmon resonances, offers a variety of potential scientific as well as industrial applications. Due to a remarkable ability to confine light at nanoscale dimensions, far below the optical diffraction limit, together with an ability to detect minute changes in the local environment plasmonic nanoparticles have paved routes towards several new and intriguing techniques, promising for future applications in areas such as molecular sensing and quantum optics.

   Sammanfattning : The magnetospheric cusps are two funnel-like regions of Earth's magnetosphere where solar wind plasma can have direct access to the ionosphere. The cusps are very dynamic regions where wave-particle interactions continuously take place and redistribute energy among different particle populations. LÄS MER

5. 4. Nuclear spin interactions and coherent control in rare-earth-ion-doped crystals for quantum computing

   Författare :Hafsa Syed; NanoLund: Centre for Nanoscience; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; rare-earth-ion-doped crystals; nuclear spins; magnetic dipole-dipole interactions; flip-flop interactions; quantum computing; high-fidelity;

   Sammanfattning : This thesis work concerns studies of two rare-earth-ions, praseodymium (Pr3+) and europium (Eu3+), doped into a yttrium orthosilicate (Y2SiO5) crystal for applications in quantum computing. The nuclear spin levels of these ions can have very long coherence times, up to several hours. LÄS MER

7. 5. Coherent Multidimensional Spectroscopy as a Probe of System-Bath Interactions

   Författare :Niklas Christensson; Kemisk fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nonlinear Spectroscopy Photon Echoes System-Bath Interactions Carotenoids;

   Sammanfattning : The interaction of molecules with their environment has a profound effect on dynamics in molecular systems. System-bath interactions, or the interaction of electronic and nuclear degrees of freedom, are important in order to understand chemical reactions and transport of energy and electrons in the condensed phase.
