Searching for dilaton dark matter with atomic clocks
We propose an experiment to search for ultralight scalar dark matter (DM) with dilatonic
interactions. Such couplings can arise for the dilaton as well as for moduli and axion-like …

Spin- Optical Lattice Clock
We experimentally investigate an optical clock based on Yb 171 (I= 1/2) atoms confined in
an optical lattice. We have evaluated all known frequency shifts to the clock transition …
