Optically-Induced Polarons in Bose-Einstein Condensates: Monitoring Composite Quasiparticle Decay
arXiv:cond-mat/0411301 · doi:10.1103/PhysRevLett.94.190403
Abstract
Nonresonant light-scattering off atomic Bose-Einstein condensates (BECs) is predicted to give rise to hitherto unexplored composite quasiparticles: unstable polarons, i.e., local ``impurities'' dressed by virtual phonons. Optical monitoring of their spontaneous decay can display either Zeno or anti-Zeno deviations from the Golden Rule, and thereby probe the temporal correlations of elementary excitations in BECs.
