Observation of millihertz-level cooperative Lamb shifts in an optical atomic clock
Collective couplings of atomic dipoles to a shared electromagnetic environment produce a
wide range of many-body phenomena. We report on the direct observation of resonant …

Fermionic matter-wave quantum optics with cold-atom impurity models
Motivated by recent cold-atom realizations of matter-wave waveguide QED, we study simple
fermionic impurity models and discuss fermionic analogs of several paradigmatic …

Coherent evolution of superexchange interaction in seconds long optical clock spectroscopy
Measurement science now connects strongly with engineering of quantum coherence, many-
body states, and entanglement. To scale up the performance of an atomic clock using a …
