Congratulations to Sandro Gödtel on finishing his PhD!

The ZARM scientist completed his doctoral thesis in the research field of gravitational physics.

In his dissertation "Constraints on short-range modified gravity with self-gravitating Bose-Einstein condensates" Sandro Gödtel analyzed the inherent of a self-gravitating Bose-Einstein condensate (BEC).  The intrinsic vibrations reveal what the gravitational force between the atoms of the condensate looks like. He used the Newton-Gross-Pitaevskii equation and calculated the intrinsic vibrations in spherically symmetric and axially symmetric configurations for different laws of gravity. He showed that there are parameter ranges that have not been tested, yet, but could give the opportunity to our BECs to explore "new physical territories". 

For Sandro, however, the doctotral thesis, was much more than just gaining a deeper understanding of a specific topic: "During my time at ZARM, I made many new friends among my colleagues and learned a lot, especially about gravitational physics. In addition, thanks to my work, I have developed an interest in programming and numerics, which is why I now want to continue my education and career in the IT field."
