Cavity Sub- and Superradiance Enhanced Ramsey Spectroscopy

  title={Cavity Sub- and Superradiance Enhanced Ramsey Spectroscopy},
  author={Christoph Hotter and Laurin Ostermann and Helmut Ritsch},
Ramsey spectroscopy in large, dense ensembles of ultra-cold atoms trapped in optical lattices suffers from dipole-dipole interaction induced shifts and collective superradiance limiting its precision and accuracy. We propose a novel geometry implementing fast signal readout with minimal heating for large atom numbers at lower densities via an optical cavity operated in the weak single atom but strong collective coupling regime. The key idea is controlled collective transverse π/2-excitation of…
