DOI: 10.1007/s10509-018-3296-z
Abstract: The interaction between the quantum vacuum and a weak gravitational field is calculated for the vacuum fields of quantum electrodynamics. The result shows that the vacuum state is modified by the gravitational field, giving rise… read more here.

DOI: 10.1038/d41586-019-01083-z
Abstract: A vacuum as described by quantum mechanics is perhaps the most fundamental but mysterious state in physics. The discovery of correlations between electric-field fluctuations in such a vacuum represents a major advance.Searching for interferences between… read more here.

DOI: 10.1103/physrevd.103.076009
Abstract: Quantum vacuum fluctuations give rise to effective non-linear interactions between electromagnetic fields. A prominent signature of quantum vacuum nonlinearities driven by macroscopic fields are signal photons differing in characteristic properties such as frequency, propagation direction… read more here.

DOI: 10.1103/physrevd.95.103504
Abstract: We investigate the gravitational property of the quantum vacuum by treating its large energy density predicted by quantum field theory seriously and assuming that it does gravitate to obey the equivalence principle of general relativity.… read more here.
