Non-perturbative analysis of entanglement harvesting from coherent field states
Petar Simidzija, Eduardo Martin-Martinez
We study (non-perturbatively) the interactions of delta-coupled detectors with coherent states of a scalar field. We show that the time-evolved density matrix spectra of i) a singl…

All coherent field states entangle equally
Petar Simidzija, Eduardo Martin-Martinez
We analyze the interactions of particle detectors with coherent states of a free scalar field. We find that the eigenvalues of the post-interaction density matrices of i) a single…
