Antimatter spectroscopy

First measurements of the line-shape of the 1s-2s in the antihydrogen atom are reported in a paper published in Nature, by the ALPHA collaboration, where Fysikum is a partner. The line shape agrees with ordinary hydrogen to a relative precision of 2x10-12, and thus puts an upper limit to the possible violation of matter-antimatter symmetries.

Emma Andersson receives a prize for pedagogical innovation

The Center for University Teacher Education and the Stockholm University Student Union together organize a contest for students about how learning and teaching at university education can be improved. Emma Andersson, PhD at the Department of Physics, has presented one of the three projects awarded this years prize.
The three recipients of the prize are Cecilia Sandin, Emma Andersson and Linnea Östensson.
We asked Emma to tell us more about the project she presented.

How did you get your idea?
