Abstract: The Bose-Einstein condensate (BEC) of excited states, provides a different platform to explore the interplay between gravity and quantum physics. In this Letter, we study the response of excited-state BECs to an external gravitational field and their dynamics under gravity when space is expanding. We reveal the anomalous response of the center-of-mass of the BEC to the gravitational field and the exotic gravity-induced accelerating expansion phenomena. We demonstrate that these effects result from the interplay among gravity, space and quantum effects. We also propose related experiments to observe these anomalies.

We find that hologrons are unstable during dynamic evolution. In searching for stable bulk excitations with attractive interactions, we find they can be constructed by the local primary operators in the boundary CFT.

Looking for the quantum aspects of gravity in the gravitational Aharonov-Bohm experiment [0.0]
We develop a comprehensive theoretical framework for the gravitational Aharonov-Bohm (AB) effect. This framework uncovers key insights into the entanglement dynamics and coherence properties of quantum systems. Our analysis suggests that the derived gravitational AB phase is consistent with classical predictions.

Testing the nonclassicality of gravity with the field of a single delocalized mass [55.2480439325792]
A setup is proposed that is based on a single delocalized mass coupled to a harmonically trapped test mass. We investigate the in-principle feasibility of such an experiment, which turns out to crucially depend on the ability to tame Casimir-Polder forces.

Perspective on Quantum Bubbles in Microgravity [40.448811194740536]
The NASA Cold Atom Laboratory (CAL) aboard the International Space Station has enabled the study of ultracold atomic bubbles. Cal experiments have been performed on CAL with an. rf-dressing technique; an alternate technique (dual-species interaction-driven bubbles) has also been proposed. Both techniques can drive discovery in the next decade of fundamental physics research in microgravity.

Accurate Determination of Hubble Attenuation and Amplification in Expanding and Contracting Cold-Atom Universes [0.0]
In the expanding universe, relativistic scalar fields are thought to be attenuated by "Hubble friction" In a contracting universe this pseudo-friction would lead to amplification. We find that the observed attenuation or amplification depends on the temporal phase of the phonon field.

Spacetime effects on wavepackets of coherent light [24.587462517914865]
We introduce an operational way to distinguish between the overall shift in the pulse wavepacket and its genuine deformation after propagation. We then apply our technique to quantum states of photons that are coherent in the frequency degree of freedom. We find that the quantum coherence initially present can enhance the deformation induced by propagation in a curved background.

Quantum interference in external gravitational fields beyond General Relativity [0.0]
We study the phenomenon of quantum interference in the presence of external gravitational fields. In the non-relativistic regime, it is possible to come across a gravitational counterpart of the Bohm-Aharonov effect. On the other hand, beyond the Newtonian approximation, the relativistic nature of gravity plays a crucial role.
