The entanglement entropy of one-dimensional systems in continuous and homogeneous space
The entanglement entropy of one-dimensional systems in continuous and homogeneous space
We introduce a systematic framework to calculate the bipartite entanglement entropy of a compact spatial subsystem in a one-dimensional quantum gas which can be mapped into a noninteracting fermion system. We show that when working with a finite number of particles N, the Renyi entanglement entropies grow as log N, …
