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…
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…
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…
Crossing Over from Attractive to Repulsive Interactions in a Tunneling Bosonic Josephson Junction
G. Spagnolli, G. Semeghini, L. Masi +9
We explore the interplay between tunneling and interatomic interactions in the dynamics of a bosonic Josephson junction. We tune the scattering length of an atomic K Bose-Ei…
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…
A blueprint for a simultaneous test of quantum mechanics and general relativity in a space-based quantum optics experiment
Sam Pallister, Simon Coop, Valerio Formichella +12
In this paper we propose an experiment designed to observe a general-relativistic effect on single photon interference. The experiment consists of a folded Mach-Zehnder interferome…
Observation of Quantum Phase Transitions with Parity-Symmetry Breaking and Hysteresis
A. Trenkwalder, G. Spagnolli, G. Semeghini +8
Symmetry-breaking quantum phase transitions play a key role in several condensed matter, cosmology and nuclear physics theoretical models. Its observation in real systems is often…
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…
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…
Electrical Control of Optical Emitter Relaxation Pathways enabled by Graphene
K. J. Tielrooij, L. Orona, A. Ferrier +16
Controlling the energy flow processes and the associated energy relaxation rates of a light emitter is of high fundamental interest, and has many applications in the fields of quan…
