Suppression of collisional decoherence
Yoav Sagi, Ido Almog, Nir Davidson
We employ a continuous dynamical decoupling scheme to suppress the decoherence induced by elastic collisions of cold atoms. Using a continuous echo pulse we achieve a thirty-fold i…
Universal Spectra of Coherent Atoms in a Recurrent Random Walk
R. Pugatch, O. Firstenberg, M. Shuker +1
The probability of a random walker to return to its starting point in dimensions one and two is unity, a theorem first proven by G. Polya. The recurrence probability -- the probabi…
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…
Elimination of the Diffraction of Arbitrary Images Imprinted on Slow Light
O. Firstenberg, M. Shuker, N. Davidson +1
We present a scheme for eliminating the optical diffraction of slow-light in a thermal atomic medium of electromagnetically induced transparency. Nondiffraction is achieved for an…
