Exploring the unification of quantum theory and general relativity with a Bose-Einstein condensate
Richard Howl, Roger Penrose, Ivette Fuentes
Despite almost a century's worth of study, it is still unclear how general relativity (GR) and quantum theory (QT) should be unified into a consistent theory. The conventional appr…
Comment on "Interaction of a Bose-Einstein condensate with a gravitational wave"
Richard Howl, Dennis Rätzel, Ivette Fuentes
A gravitational-wave (GW) detector that utilizes the phononic excitations of a Bose-Einstein condensate (BEC) has recently been proposed [NJP 16, 085003 (2014)]. A subsequent and i…
Evolution of confined quantum scalar fields in curved spacetime. Part I
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…
Quantum-metrology estimation of spacetime parameters of the Earth outperforming classical precision
Jan Kohlrus, David Edward Bruschi, Ivette Fuentes
We consider quantum communication schemes where quantum optical signals are exchanged between a source on Earth and a satellite. The background curved spacetime affects the quantum…
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…
Wigner phase of photonic helicity states in the spacetime of the Earth
Jan Kohlrus, Jorma Louko, Ivette Fuentes +1
We study relativistic effects on polarised photons that travel in a curved spacetime. As a concrete application, we consider photons in the gravitational field of the Earth, on a c…
