Absolute frequency references at 1529 nm and 1560 nm using modulation transfer spectroscopy
Y. Natali Martinez de Escobar, Silvana Palacios Ãlvarez, 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…
Interferometric measurement of interhyperfine scattering lengths in Rb
Pau Gomez, Chiara Mazzinghi, Ferran Martin +3
We present interferometeric measurements of the to inter-hyperfine scattering lengths in a single-domain spinor Bose-Einstein condensate of Rb. The inter-hyperfi…
Single-domain Bose condensate magnetometer achieves energy resolution per bandwidth below
Silvana Palacios Alvarez, Pau Gomez, Simon Coop +3
We present a magnetic sensor with energy resolution per bandwidth . We show how a single domain spinor Bose-Einstein condensate, detected by non-des…
Spontaneous PT symmetry breaking of a ferromagnetic superfluid in a gradient field
Thomas Vanderbruggen, Silvana Palacios, Simon Coop +2
We consider the interaction of a ferromagnetic spinor Bose-Einstein condensate with a magnetic field gradient. The magnetic field gradient realizes a spin-position coupling that ex…
Multi-second magnetic coherence in a single domain spinor Bose-Einstein condensate
Silvana Palacios, Simon Coop, Pau Gomez +4
We describe a compact, robust and versatile system for studying magnetic dynamics in a spinor Bose-Einstein condensate. Condensates of 87 Rb are produced by all-optical evaporation…
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…
