2. Optical Imaging and Spectroscopy of Metal Nanostructures
Sammanfattning : Noble metal structures with size in the sub 100 nm range exhibit extraordinary optical properties due to collective oscillations of conduction electrons, the surface plasmon resonances (SPR). The most remarkable feature of these structures is the ability to redistribute electromagnetic radiation and concentrate strong fields near the surface. LÄS MER
3. Broadband Ferromagnetic Resonance Spectrometer : Instrument and Applications
Sammanfattning : This thesis compiles results of research in two mutuallydependent parts: 1) development of ferromagnetic resonance(FMR) spectrometer to study microwave properties offerromagnetic materials, and 2) characterization of new irongarnets: pulsed laser deposited Y3Fe5O12and Bi3Fe5O12films and Ce:Y3Fe5O12single crystal.First part describes a novelBroadbandFMRSpectrometerdesigned to characterize thin ferromagneticfilms.

5. Atomic transport in optical lattices
Sammanfattning : This thesis includes both experimental and theoretical investigations of fluctuation-induced transport phenomena, presented in a series of nine papers, by studies of the dynamics of cold atoms in dissipative optical lattices. With standard laser cooling techniques about 108 cesium atoms are accumulated, cooled to a few μK, and transferred into a dissipative optical lattice. LÄS MER
