Gravitational time dilation in extended quantum systems: the case of light clocks in Schwarzschild spacetime
Tupac Bravo, Dennis Rätzel, Ivette Fuentes
The precision of optical atomic clocks is approaching a regime where they resolve gravitational time dilation on smaller scales than their own extensions. Hence, an accurate descri…
Quantum-enhanced screened dark energy detection
Daniel Hartley, Christian Käding, Richard Howl +1
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 d…
AEDGE: Atomic Experiment for Dark Matter and Gravity Exploration in Space
Yousef Abou El-Neaj, Cristiano Alpigiani, Sana Amairi-Pyka +129
We propose in this White Paper a concept for a space experiment using cold atoms to search for ultra-light dark matter, and to detect gravitational waves in the frequency range bet…
Quantum simulation of dark energy candidates
Daniel Hartley, Christian Käding, Richard Howl +1
Additional scalar fields from scalar-tensor, modified gravity or higher dimensional theories beyond general relativity may account for dark energy and the accelerating expansion of…
Analogue simulation of gravitational waves in a 3+1 dimensional Bose-Einstein condensate
Daniel Hartley, Tupac Bravo, Dennis Rätzel +2
The recent detections of gravitational waves (GWs) by the LIGO and Virgo collaborations have opened the field of GW astronomy, intensifying interest in GWs and other possible detec…
Frequency spectrum of an optical resonator in a curved spacetime
Dennis Rätzel, Fabienne Schneiter, Daniel Braun +4
The effect of gravity and proper acceleration on the frequency spectrum of an optical resonator - both rigid or deformable - is considered in the framework of general relativity. T…
