Quantum-enhanced screened dark energy detection

Understand

We propose an experiment based on a Bose-Einstein condensate interferometer for strongly constraining fifth-force models.

• Additional scalar fields from modified gravity or higher dimensional theories may account for dark energy and the accelerating expansion of the Universe.
• These theories have led to proposed screening mechanisms to fit within the tight experimental bounds on fifth-force searches.
• We show that our proposed experiment would greatly improve the existing constraints on these screening models by many orders of magnitude.
