# Quantum principle of sensing gravitational waves: From the zero-point fluctuations to the cosmological stochastic background of spacetime

@article{Quiones2017QuantumPO, title={Quantum principle of sensing gravitational waves: From the zero-point fluctuations to the cosmological stochastic background of spacetime}, author={D A Qui{\~n}ones and Teodora Oniga and Benjamin T. H. Varcoe and Charles H.-T. Wang}, journal={Physical Review D}, year={2017}, volume={96}, pages={044018} }

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 gravitational waves. A general approach is taken with the derivation of a quantum master equation capable of describing arbitrary confined nonrelativistic matter systems in an open quantum gravitational environment. It enables us to relate the spectral function for gravitational waves and the distribution function for quantum…
