Short-Time Enhanced Decay of Coherent Excitations in Bose-Einstein Condensates
Nir Bar-Gill, Eitan E. Rowen, Gershon Kurizki +1
We study, both experimentally and theoretically, short-time modifications of the decay of excitations in a Bose-Einstein Condensate (BEC) embedded in an optical lattice. Strong enh…
Spectroscopy of Strong-Pulse Superradiance in a Bose-Einstein condensate
Nir Bar-Gill, Eitan E. Rowen, Nir Davidson
We study experimentally superradiance in a Bose-Einstein condensate using a two-frequency pump beam. By controlling the frequency difference between the beam components, we measure…
Dressed state approach to matter wave mixing of bosons
E. Rowen, R. Ozeri, N. Katz +2
A dressed state approach to mixing of bosonic matter waves is presented. Two cases are studied using this formalism. In the first, two macroscopically populated modes of atoms (two…
Collisional decay of a strongly driven Bose-Einstein condensate
Nadav Katz, Eitan Rowen, Roee Ozeri +1
We study the collisional decay of a strongly driven Bose-Einstein condensate oscillating between two momentum modes. The resulting products of the decay are found to strongly devia…
Optically-Induced Polarons in Bose-Einstein Condensates: Monitoring Composite Quasiparticle Decay
I. E. Mazets, G. Kurizki, N. Katz +1
Nonresonant light-scattering off atomic Bose-Einstein condensates (BECs) is predicted to give rise to hitherto unexplored composite quasiparticles: unstable polarons, i.e., local `…
