Entanglement scaling for $\lambda {\varphi }_2^4$

Bram Vanhecke, Frank Verstraete, Karel Van Acoleyen

We study the $\lambda {\varphi }^4$ model in $0+2$ dimensions at criticality, and effectuate a simultaneous scaling of UV and IR physics. We demonstrate that the order parameter $\varphi$, the correlati…
