In this talk I will review past and current experiments on the QED vacuum. The fluctuations of QFT vacuum are one of the hallmarks of field theory, and they carry with them a host of important implications. Photon-photon scattering -- in all its incarnations -- is a powerful tool to study these fluctuations in QED. Moreover, interactions of photons with yet-to-be detected pseudoscalar...

The Pauli Exclusion Principle (PEP) is one of the most fundamental pillars of physics and it has tremendous consequences - from the stability of matter to atomic and subatomic systems. According to many observations PEP must be valid to an extremely high degree and no violations were found up to now. On the other hand a simple explanation of PEP is missing. Numerous experimental investigations...

Four (known) forces are ruling our Universe; the weak interaction is the only one violating discrete symmetries. This talk presents a surprising relation between the violation of such symmetries and various foundational concepts of quantum mechanics for spin-less (mesons) and spin particles (hyperons). These systems show also an unexpected and puzzling relation to another big open question:...

Collapse models are phenomenological models where the collapse of the wave function is described through a non linear interaction with an external classic noise. Because of the interaction with this noise, collapse models make different predictions compared to Quantum Mechanics. In the Continuous Spontaneous Localization (CSL) collapse model, the strength of the noise effects is measured by...
