- 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.

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.

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.

The entanglement harvesting protocol is an operational way to probe vacuum entanglement.
Using this protocol, it is demonstrated that while the transition probability of an individual atom is unaffected by the presence of a gravitational wave, the entanglement harvested by two atoms depends sensitively on the frequency of the gravitational wave.
This suggests that the entanglement signature left by a gravitational wave may be useful in characterizing its properties, and potentially useful in exploring the gravitational-wave memory effect and gravitational-wave induced decoherence.
