2. 1. Cold atoms in a variety of optical lattice potentials

   Author : Robert Saers; Umeå universitet; []
   Keywords : ;

   Abstract : In this thesis, both experimental achievements and theoretical preparatory investigationsfor future experiments are introduced. The experiments presentedare performed with the set-up used for laser cooling and trapping of rubidiumatoms, and the theoretical examinations are adopted for intended experimentson Bose-Einstein Condensates.

4. 2. Ultracold rubidium atoms in periodic potentials

   Author : Robert Saers; Anders Kastberg; Svante Jonsell; Jan W. Thomsen; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bose-Einstein condensation; optical lattice; quantum phase transition; experiment; theory; Condensed matter physics; Kondenserade materiens fysik;

   Abstract : This thesis includes both experimental and theoretical investigations, presented in a series of eight papers. The experimental part ranges from the construction procedures of an apparatus for Bose-Einstein condensates, to full scale experiments using three different set-ups for ultracold atoms in optical lattices.

5. 3. Effect of HV Impulses on Partial Discharge Activity in Oil-Impregnated Paper Insulation

   Author : Respicius Clemence Kiiza; Hans Edin; Robert Saers; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : High voltage (HV) transients in electrical power systems are mainly caused by lightning strikes and switching operations.  The high voltage transient from its point of origin can propagate in either direction in the electrical power transmission line, and if its magnitude would be below the Basic Insulation Level (BIL) of the equipment for impulse voltage, it can reach the terminals of the equipment without being dissipated by surge arresters.
