4th Quarter 2012: The research building is coming!

 

1st Quarter 2013 - Four Electron Neutrino Candidates

 

2nd Quarter 2013 - Emergent randomness from strong electronic interactions

In a number of complex materials strong electron interactions induce a metal-to-insulator transition, the so-called Mott-Hubbard transition. Near this 1st-order transition, insulating nanodomains coexist with metallic regions, just like ice cubes can exist in a glass of water.

4th Quarter 2013 - Wolfgang Paul Symposium

Wolfgang Paul was born on August 10, 1913 in Lorenzkirch, Saxony. On the occasion of his 100th birthday this year, a three day symposium will be held in his memory on November 11 – 13, 2013.

1st Quarter 2014 - Two ERC prize winners

This year the Physics Institute of the University of Bonn succeeded in winning two ERC (European Research Council) projects. In one of the supported projects Markus Cristinziani will investigate the interaction between top quarks and neutral bosons in the search for new physics while Michael Köhl explores new creation mechanisms of superfluidity and superconductivity. Each projected is funded with 2 million Euro.

2nd Quarter 2014 - DEPFET Matrix

The first large, thin, multi-chip DEPFET (DEpleted P-channel Field Effect Transistor) detector arrived in Bonn for further optimization and characterization. The sensor consists of roughly 92 thousand DEPFET pixels arranged in 192 columns and 480 rows with a pitch of 50 x 75 um, resulting in a total sensitive area of 36.0 x 9.6 mm.

3rd Quarter 2014 - InGrid Detector

The CAST experiment at CERN searches for axions and chameleons, hypothetical particles which are related to dark matter and dark energy. The experiment is now equipped with a new detector (InGrid detector, a gas-filled pixel detector) for soft X-rays which was built by the Physikalisches Institut

4th Quarter 2014 - ATLAS Pixel Detector

This is the innermost layer of the ATLAS pixel detector being installed in May 2014. It is only 3.5 cm away from the interaction point and needs to withstand extreme rates and irradiation doses.

2nd Quarter 2015 - Plasmonic Waves

Coupled arrays of plasmonic waveguides can be used as a model system to study random media. The transport properties of the plasmon waves are changed by disorder.

2nd Quarter 2016 - Physics Show for Refugees in Bonn

Physics show for refugees in Bonn - On 20 December 2015 physics students performed a physics show for refugees in Bonn here in the Physics Insitute. It was carried out in arabic and english interchanging the two languages. The show was a great success and the refugees liked it a lot.

3rd Quartal 2016 - Local density of a 2D Fermi-Hubbard atomic gas in an optical lattice potential

 

4th Quartal 2016 - Inflationary quasiparticle creation and thermalization in oscillating Bose-Einstein condensates

 

1st Quarter 2017 - Foundation stone ceremony at FTD

Foundation stone ceremony for the new Research and Technology Center for Detectorphysics (FTD)

2nd Quarter 2017 - New beam line for detector tests at ELSA

Completion and first operation of the new beam line for detector tests at ELSA
