The area and volume laws for entanglement of scalar fields in flat and cosmological spacetimes
K. Andrzejewski
We study the area and volume laws for entanglement of free quantum scalar fields. In addition to the entropy, we use the notion of the capacity of entanglement, which measures entr…

Evolution of capacity of entanglement and modular entropy in harmonic chains and scalar fields
K. Andrzejewski
We examine the temporal evolution of the modular entropy and capacity (in particular, the fluctuation of the entanglement entropy) for systems of time-dependent oscillators coupled…
