Loss of coherence of matter-wave interferometer from fluctuating graviton bath
In this paper we consider non-relativistic matter-wave interferometer coupled with a quantum graviton bath $\mathord{-}$ and discuss the loss of coherence in the matter sector due to theExpand
Gravitational dephasing in spontaneous emission of atomic ensembles in timed Dicke states
Here we discuss an effect of gravitational decoherence due to time dilation on the collective radiation dynamics of atomic system in timed single-photon Dicke states. We show that a photon absorbedExpand
Cosmic Quantum Optical Probing of Quantum Gravity Through a Gravitational Lens
We consider the nonunitary quantum dynamics of neutral massless scalar particles used to model photons around a massive gravitational lens. The gravitational interaction between the lensing mass andExpand
Neutrino signals of lightcone fluctuations resulting from fluctuating space-time
One of the most common expectations of a quantum theory of gravity is that space-time is uncertain or fluctuating at microscopic scales, making it a stochastic medium for particle propagation.Expand
Unitary Representations of the Translational Group Acting as Local Diffeomorphisms of Space-Time
One way of eliminating the infinities of renormalisation is through assuming a form of supersymmetry (SUSY) in which additional ‘spinor charge observables’ are added to the Lie algebra of theExpand
Unitary Representations of the Translational Group Acting as Local Diffeomorphisms of Space-Time
We continue to develop further a new mathematical approach to the quantisation of general field theories such as general relativity and modified gravity. Treating quantum fields as fibre bundles, weExpand
Bremsstrahlung of Light through Spontaneous Emission of Gravitational Waves
It is suggested that this new effect may be important for a combined astronomical source of intense gravity and high-frequency radiation such as X-ray binaries and that the proposed LISA mission may be potentially sensitive to the resulting sub-Hz stochastic gravitational waves. Expand
Noise and decoherence induced by gravitons
We study quantum noise and decoherence induced by gravitons. We derive a Langevin equation of geodesic deviation in the presence of gravitons. The amplitude of noise correlations tells us that largeExpand

It is shown that gravity as an environment induces the rapid decoherence of stationary matter superposition states when the energy differences in the superposition exceed the Planck energy scale. Expand

Decoherence induced by long wavelength gravitons
We discuss how a background bath of gravitons can induce decoherence of quantum systems. The mechanism is dephasing, the loss of phase coherence due to quantum geometry fluctuations caused by theExpand
