Key static and dynamic properties of matter—from creation in the Big Bang to evolution into
subatomic and astrophysical environments—arise from the underlying fundamental …

One of the best signatures of nonclassicality in a quantum system is the existence of
correlations that have no classical counterpart. Different methods for quantifying the …

It has been 30 years since the discovery of the Unruh effect. It has played a crucial role in
our understanding that the particle content of a field theory is observer dependent. This …

We analyze the harvesting of entanglement and classical correlations from the quantum
vacuum to particle detectors. We assess the impact on the detectors' harvesting ability of the …

We propose a measurement theory for quantum fields based on measurements made with
localized nonrelativistic systems that couple covariantly to quantum fields (like the Unruh …

We study the protocol of entanglement harvesting when the particle detectors that harvest
entanglement from the field are replaced by fully relativistic quantum field theories. We show …

We study how two fully featured hydrogenlike atoms harvest entanglement from the
electromagnetic field vacuum, even when the atoms are spacelike separated. We compare …

We show that entanglement can be used to detect spacetime curvature. Quantum fields in
the Minkowski vacuum are entangled with respect to local field modes. This entanglement …

We study entanglement harvested from a quantum field through local interaction with Unruh–
DeWitt detectors undergoing linear acceleration. The interactions allow entanglement to be …

We propose a fully covariant model for smeared particle detectors in quantum field theory in
curved spacetimes. We show how effects related to accelerated motion of the detector and …
