We discuss various all-optical probes of quantum vacuum nonlinearity in strong electromagnetic fields. Our focus is on signatures of quantum vacuum nonlinearity in inhomogeneous field profiles, as attainable in the focal spots of realistic high-intensity laser experiments.

The CAST experiment is designed to search for solar axions which are produced in the interior of the sun via the Primakoff effect. The central part of the experiment, the helioscope is an LHC prototype magnet that has attached different types of sensitive detectors for x-rays in the regime of 1-10 keV. The experiment has been taking data since 2003 and provided the most restrictive limits on the a ... More

A new highly sensitive ellipsometer is now running at the Department of Physics and INFN of Ferrara, Italy. The apparatus has been designed to detect very small magnetically induced birefringences with the ultimate goal of measuring vacuum magnetic birefringence. This challenging goal is not yet achievable due to excess noise which is under study. Nonetheless new limits on vacuum magnetic birefrin ... More

One of the simplest Standard Model extensions consists in a `Hidden Photon', coupled kinetically to the photon of the Standard Model. Such a particle could also constitute the Dark Matter. We highlight the most important theoretical and phenomenological aspects of ultra-light Hidden Photons and report on two upcoming experimental searches for such particles at DESY Hamburg (ALPS-II) and the ...
