The ASACUSA collaboration at the Antiproton Decelerator of CERN is planning to measure the ground- state hyperfine splitting of antihydrogen using an atomic beam line. The setup consists of a cusp trap as a source of partially polarized antihydrogen atoms emitted toward a radiofrequency spin-flip cavity. A superconducting sextupole magnet serves as spin analyser before the detection of the...

Antiprotonic helium [1] is an exotic three-body system consisting of a helium nucleus, an electron and an antiproton. The antiproton occupies highly excited metastable states, which allows it to be studied by laser and microwave spectroscopy techniques. By comparing the experimental results with state-of-the-art three-body QED calculations, fundamental properties of the antiproton can be...

One of the fundamental rules of nature and a pillar in the foundation of quantum theory
and thus of modern physics is represented by the Pauli Exclusion Principle.
We know that this principle is extremely well fulfilled due to many observations. Numerous experiments were performed to search for tiny violation of this rule in various systems. The experiment VIP at the Gran Sasso underground...

In arXiv:1211.3152, we present a new perturbative formulation of non-equilibrium thermal field theory, based upon non-homogeneous free propagators and time-dependent vertices. The resulting time-dependent diagrammatic perturbation series are free of pinch singularities without the need for quasi-particle approximation or effective resummation of finite widths. Introducing a physically...
