Emerging Spacetime from Quantum Field Theory

Abstract

This article provides some glimpses of recent developments towards understanding the emergence of spacetime from quantum many-body dynamics. The idea goes under the name of Gauge/Gravity or Gauge/String duality. In this article, I review two recent developments that took place during the past decade, namely, the quantum entanglement and quantum complexity in strongly coupled Quantum Field Theories and their interplay with the gravitational dynamics in one higher dimension.
