header_image.jpg The basic premise of our work is that precision measurements of fundamental quantities can help physicists to address the great challenges they face now - for example, to find and verify a theory beyond the standard model of particle physics that might eventually unify gravity and quantum mechanics. While the energy scale of such theories is typically beyond the reach of experiments, it is possible to probe for suppressed effects at attainable energies in experiments of outstanding precision. Precision measurements have been playing a central role in the shifts of the paradigms in physics in the twentieth century and we, among others, will make sure that this will continue in the twenty-first. Our work applies methods from atomic, molecular, and optical physics. It is centered on advancing the experimental technology to push the sensitivity of experiments to new levels, and to perform precision measurements of fundamental quantities. Examples are atom interferometry and testing Lorentz invariance. We also work on the theory required for or underlying this work. Besides, we want to set up working with femtosecond lasers, especially frequency comb metrology and using broadband coherent radiation from femtosecond lasers to access transitions in all regions of the spectrum, in collaboration with Lawrence Berkeley National Laboratory. We are also working on cutting edge electronics and optoelectronics, see the list of publications. We believe ours is a rewarding workplace to be in, because it combines the possibility to do experiments on one's own or with a few collaborators with the thrill of exploring new ground in fundamental physics.
