Entanglement Renormalization and Two Dimensional String Theory (1510.09020v3)
Published 30 Oct 2015 in hep-th, cond-mat.str-el, and quant-ph
Abstract: The entanglement renormalization flow of a (1+1) free boson is formulated as a path integral over some auxiliary scalar fields. The resulting effective theory for these fields amounts to the dilaton term of non-critical string theory in two spacetime dimensions. A connection between the scalar fields in the two theories is provided, allowing to acquire novel insights into how a theory of gravity emerges from the entanglement structure of another one without gravity.
