Strong light shifts from near-resonant and polychromatic fields: comparison of Floquet theory and experiment
Simon Coop, Silvana Palacios, Pau Gomez +3
We present a non-perturbative numerical technique for calculating strong light shifts in atoms under the influence of multiple optical fields with arbitrary polarization. We confir…
Absolute frequency references at 1529 nm and 1560 nm using modulation transfer spectroscopy
Y. Natali Martinez de Escobar, Silvana Palacios Álvarez, Simon Coop +3
We demonstrate a double optical frequency reference (1529 nm and 1560 nm) for the telecom C-band using Rb modulation transfer spectroscopy. The two reference frequencies are…
Feedback control of coherent spin states using weak nondestructive measurements
Thomas Vanderbruggen, Ralf Kohlhaas, Andrea Bertoldi +3
We consider the decoherence of a pseudo-spin ensemble under collective random rotations, and study, both theoretically and experimentally, how a nondestructive measurement combined…
Near-resonant optical forces beyond the two-level approximation for a continuous source of spin-polarized cold atoms
Thomas Vanderbruggen, Morgan Mitchell
We propose a method to generate a source of spin-polarized cold atoms which are continuously extracted and guided from a magneto-optical trap using an atom-diode effect. We show th…
Feedback control of trapped coherent atomic ensembles
T. Vanderbruggen, R. Kohlhaas, A. Bertoldi +4
We demonstrate how to use feedback to control the internal states of trapped coherent ensembles of two-level atoms, and to protect a superposition state against the decoherence ind…
