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…
Evolution of confined quantum scalar fields in curved spacetime. Part II
Luis C. Barbado, Ana L. Báez-Camargo, Ivette Fuentes
We develop a method for computing the Bogoliubov transformation experienced by a confined quantum scalar field in a globally hyperbolic spacetime, due to the changes in the geometr…
Phononic gravity gradiometry with Bose-Einstein condensates
Tupac Bravo, Dennis Rätzel, Ivette Fuentes
Gravity gradiometry with Bose-Einstein condensates (BECs) has reached unprecedented precisions. The basis of this technique is the measurement of differential forces by interferenc…
General solution of the time evolution of two interacting harmonic oscillators
David Edward Bruschi, G. S. Paraoanu, Ivette Fuentes +2
We study the time evolution of an ideal system composed of two harmonic oscillators coupled through a quadratic Hamiltonian with arbitrary interaction strength. We solve its dynami…
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…
