Evidence of quantum phase transition in real-space vacuum entanglement of higher derivative scalar quantum field theories
In a bipartite set-up, the vacuum state of a free Bosonic scalar field is entangled in real space and satisfies the area-law— entanglement entropy scales linearly with area of the boundary between the two partitions. In this work, we show that the area law is violated in two spatial dimensional mode...
