Description
We investigate quantum entanglement in a one-dimensional cavity with an accelerating boundary, serving as a model of Hawking-like particle creation. Employing logarithmic negativity, we study correlations between selected modes and the rest of the field, and for pure states we reconstruct partner modes using the Hotta-Schützhold-Unruh relation. By analyzing vacuum, squeezed, and thermal initial states, we show that the dynamical cavity acts as an effective squeezing device and that Hawking-partner pairs closely resemble two-mode squeezed states. Our simulations indicate that entanglement is dominated by low-energy modes, while ultraviolet modes contribute negligibly to purification. The results also show that entanglement decreases with increasing mode energy in both small- and large-acceleration regimes, as well as we highlight the limitations of a purely pairwise description in the presence of multimode correlations.
