Stimulated absorption of single gravitons: First light on quantum gravity

Victoria Shenderov, Mark Kanex, Thomas Beitel +3

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…

Detecting kHz gravitons from a neutron star merger with a multi-mode resonant mass detector

Germain Tobar, Igor Pikovski, Michael Edmund Tobar

We propose a multi-mode bar consisting of mass elements of decreasing size for the implementation of a gravitational version of the photo-electric effect through the stimulated abs…

Detecting single gravitons with quantum sensing

Germain Tobar, Sreenath K. Manikandan, Thomas Beitel +1

The quantization of gravity is widely believed to result in gravitons -- particles of discrete energy that form gravitational waves. But their detection has so far been considered…

Testing spontaneous wavefunction collapse with quantum electromechanics

Germain Tobar, Stefan Forstner, Arkady Fedorov +1

Theories of spontaneous wavefunction collapse offer an explanation of the possible breakdown of quantum mechanics for macroscopic systems. However, the challenge of resolving predi…

Mass-energy equivalence in gravitationally bound quantum states of the neutron

Germain Tobar, Simon Haine, Fabio Costa +1

Gravitationally bound neutrons have become an important tool in the experimental searches for new physics, such as modifications to Newton's force or candidates for dark matter par…

Reversible dynamics with closed time-like curves and freedom of choice

Germain Tobar, Fabio Costa

The theory of general relativity predicts the existence of closed time-like curves (CTCs), which theoretically would allow an observer to travel back in time and interact with thei…
