| 英文摘要 | We study the entanglement entropy associated to the phonons generated via the Hawking mechanism of acoustic black holes in a Bose-Einsten condensate. The lowest energy allowed for the radiated phonons is found to be a function of space coordinate. Based this, we calculate the entanglement entropy, which contains three parts: a leading term, which is a constant of value 1/6, a logarithmic correction term and some series terms. We discuss the convergence of the series terms. |
