  5. 4. Laser cooling mechanisms and Brownian motors in optical lattices

    Författare :Peder Sjölund; Anders Kastberg; Svante Jonsell; Chris Westbrook; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical physics; Optisk fysik;

    Sammanfattning : Denna avhandling innefattar såväl experimentella som numeriska studier av laserkylda atomer i optiska kristallgitter. Bland annat har laserkylningsprocesser studerats, där atomers rörelser i optiska kristallgitter har uppvisat andra typer av bakomliggande mekanismer än de som tidigare förutsågs genom “Sisyfoskylningsmodellen”.
