# Observation of the quantum zeno and anti-zeno effects in an unstable system

@article{GutirrezMedina2001ObservationOT, title={Observation of the quantum zeno and anti-zeno effects in an unstable system}, author={Braulio Guti{\'e}rrez-Medina and Martin C. Fischer and Mark Raizen}, journal={Technical Digest. Summaries of papers presented at the Quantum Electronics and Laser Science Conference. Postconference Technical Digest (IEEE Cat. No.01CH37172)}, year={2001}, pages={QPD1-QPD1} }

We study the motion of ultra-cold atoms in an accelerating optical lattice. We find that the tunneling dynamics are strongly affected by repeated measurement during the non-exponential time, leading to either inhibition (zeno) or enhancement (anti-zeno) of decay.
