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…
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…
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…
Analog quantum simulation of gravitational waves in a Bose-Einstein condensate
Tupac Bravo, Carlos Sabín, Ivette Fuentes
We show how to vary the physical properties of a Bose-Einstein condensate (BEC) in order to mimic an effective gravitational-wave spacetime. In particular, we focus in the simulati…
