DoIT is a representation run by PhD students. We are in close contact with the DESY Directorate and other (administrative) bodies at DESY. We can give advice on all things concerning PhD students.

The ALPS (Any Light Particle Search) experiment, located at DESY, goes in its second phase. To increase the sensitivity the experiment will be bigger and fancier: more laser power, a regeneration cavity and longer cavities. Besides of that improvements the collaboration is also looking for a new, more sensitive detector.
Because of the intrinsic noise of the CCD -- the present detector of...

Cosmic rays with energies up to 10^20 eV have been seen by the Pierre Auger Collaboration and other experiments. There are still many unanswered question concerning cosmic rays in this ultra-high-energy regime. For instance the measured structure of the flux, the incoming direction and the composition of the cosmic rays still bare question-marks. A possible explanation for these three...

Finsler spacetime manifolds are generalizations of Lorentz spacetime manifolds due to the use of Finsler geometry instead of Lorentz geometry. In this talk I present results on the propagation of the free scalar field on Finsler spacetimes.
On a specific Finsler spacetime that is a small departure from Minkowski spacetime I present the dispersion relation of the particle modes of the free...

In this talk I will present new, exact tunneling solutions for different potentials. I will also comment on applications in cosmology.

We derive a sufficient condition for realizing meta-stable de Sitter vacua with small positive cosmological constant within type IIB string theory flux compactifications with spontaneously broken supersymmetry. There are a number of `lamp post' constructions of de Sitter vacua in type IIB string theory and supergravity. We show that one of them -- the method of `K\"ahler uplifting' by F-terms...
