LHC shows that our vacuum is not empty, but filled with (maybe various) fields, and these vacuum fields play important roles for cosmology and particle physics. We probe new unknown vacuum filed (for examples, Axion, Dilaton, QED) with various center of mass energies, wide range between 1μeV-1MeV, using powerful light source, XFEL, strong Magnets (see Photo below) and Positronium atom. These experimental setups are small as tabletop size. New approaches for particle physics are introduced in this seminar.
