Enhanced primordial gravitational waves from a stiff postinflationary era due to an oscillating inflaton
We investigate two classes of inflationary models, which lead to a stiff period after inflation

Testing whether gravity acts as a quantum entity when measured
A defining signature of classical systems is “in principle measurability” without disturbance: a
feature manifestly violated by quantum systems. We describe a multi-interferometer …

Detecting kHz gravitons from a neutron star merger with a multi-mode resonant bar
We propose a multi-mode bar consisting of mass elements of decreasing size for the direct
detection of stimulated absorption of up to kHz gravitons from a neutron star merger and post …

Comments on graviton detection
D Carney - arxiv preprint arxiv:2408.00094, 2024 - arxiv.org
It is possible to make a detector which clicks after absorbing a single graviton. Similarly, it is
possible to make a gravitational wave detector which can see the quantum noise induced by …

Searching for high-frequency gravitational waves with phonons
The gravitational wave (GW) spectrum at frequencies above a kHz is a largely unexplored
frontier. We show that detectors with sensitivity to single-phonon excitations in crystal targets …

Stimulated absorption of single gravitons: First light on quantum gravity
V Shenderov, M Suppiah, T Beitel, G Tobar… - arxiv preprint arxiv …, 2024 - arxiv.org
In a recent work we showed that the detection of the exchange of a single graviton between
a massive quantum resonator and a gravitational wave can be achieved. Key to this ability …

A quantum description of wave dark matter
We outline a fundamentally quantum description of bosonic dark matter (DM) from which the
conventional classical-wave picture emerges in the limit $ m\ll 10~\textrm {eV} $. As …
