Area law of noncritical ground states in 1D long-range interacting systems

The entanglement in non-critical ground states is conjectured to obey the area law, which is believed to arise from the short-range nature of interactions. Here the authors prove that the entanglement area law rigorously holds in one-dimensional systems even in the presence of long-range interaction...
