SUMMARY:Cavity-enabled measurements and interactions in neutral atoms\
 , Atomic Physics Seminar\, Zhenjie Yan\, UC Berkeley
DESCRIPTION:Control over interactions and measurements in quantum syst
 ems is crucial for applications such as quantum simulation and computa
 tion. In this talk\, I will highlight our recent progress in realizing
  nondestructive readout and long-range interactions in atomic tweezer 
 arrays using a strongly coupled optical cavity. Through selectively co
 upling a single atom with the cavity mode\, we achieve a rapid mid-cir
 cuit measurement without perturbing the quantum coherence of the other
  atoms. Conversely\, the collective emission from multiple atoms into 
 the cavity can be coherently enhanced or suppressed. By controlling th
 e atom-cavity interaction at the single-atom level\, we observe both s
 uper- and subradiant cavity emissions from the constructed atomic ense
 mbles. I will then discuss how we engineer long-range mechanical inter
 actions via photon exchange and present our recent observation of a se
 lf-organization phase transition in a mesoscopic system. Finally\, I w
 ill discuss how the cavity can be used to monitor and manipulate stron
 gly interacting quantum gases\, opening new avenues for experimental r
 esearch in quantum many-body physics.
