23. Kalla atomer

Anders Kastberg

Vad spelar det för roll vilken temperatur en samling atomer har? När atomer har kylts ner till så låga temperaturer att deras inbördes rörelse i stort sett har upphört, eller åtminstone är sådan att den endast kan beskrivas korrekt med kvantmekanik, så visar det sig att helt ny möjligheter öppnas för “atomfysik”. De kalla atomerna ger oss dels ett helt nytt instrument att studera...

22. New perspectives for atomic, molecular and optical physics with x-ray free-electron laser sources

The invention of x-ray free-electron lasers (XFELs) – new femtosecond x-ray sources with peak intensities nine orders of magnitude higher than the hitherto brightest accelerator based synchrotron x-ray sources – hold the potential of probing chemical reaction dynamics on unprecedented short time and length scales. A particular intriguing perspective is the transfer of powerful nonlinear...

38. Optical levitation of charged droplets

Oscar Isaksson (Chalmers)

The development of an experimental system used to investigate charged droplets is presented. The experimental setup combines optical levitation with Millikan's classical oil drop experiment and has also been used as a mean to demonstrate fundamental physical phenomena. Oil or water droplets are trapped in a vertical laser beam where their sizes can be determined. A vertical electric field is...
