Cosmic quantum optical probing of quantum gravity through a gravitational lensLens
Charles H. -T. Wang, Elliott Mansfield, Teodora Oniga
We consider the nonunitary quantum dynamics of neutral massless scalar particles used to model photons around a massive gravitational lens. The gravitational interaction between th…
Quantum principle of sensing gravitational waves: From the zero-point fluctuations to the cosmological stochastic background of spacetime
Diego A. Quinones, Teodora Oniga, Benjamin T. H. Varcoe +1
We carry out a theoretical investigation on the collective dynamics of an ensemble of correlated atoms, subject to both vacuum fluctuations of spacetime and stochastic gravitationa…
Quantum coherence, radiance, and resistance of gravitational systems
Teodora Oniga, Charles H. -T. Wang
We develop a general framework for the open dynamics of an ensemble of quantum particles subject to spacetime fluctuations about the flat background. An arbitrary number of interac…
Ergodic Theory and the Structure of Noncommutative Space-Time
James Moffat, Teodora Oniga, Charles H. -T. Wang
We develop further our fibre bundle construct of non-commutative space-time on a Minkowski base space. We assume space-time is non-commutative due to the existence of additional no…
Quantum dynamics of bound states under spacetime fluctuations
Teodora Oniga, Charles H. -T. Wang
With recent developments in high-precision quantum measurements, the question of whether observations of decoherence from spacetime fluctuations are accessible experimentally arise…
Unitary Representations of the Translational Group Acting as Local Diffeomorphisms of Space-Time
James Moffat, Teodora Oniga, Charles H. -T. Wang
We develop a new mathematical approach to diffeomorphism invariant quantum states for the quantisation of general field theories such as general relativity and modified gravity. Tr…
