Abstract: 

In this talk, I will introduce the recent development of the entanglement feature formalism in describing the structure and dynamics of quantum many-body entanglement. Understanding how quantum entanglement is generated and distributed across quantum many-body systems is a quest shared by condensed matter physics, quantum gravity theory, and quantum information science. The entanglement feature is a new theoretical tool to systematically organize the entanglement properties in a quantum many-body system using a fictitious many-body state of entanglement regions. In this framework, the evolution of entanglement entropy can be described by the imaginary-time evolution of a quantum many-body system of entanglement cuts. I will illustrate the usefulness of the entanglement feature formalism with three examples: efficiently simulating entanglement dynamics, understanding the nature of entanglement transition, reconstructing emergent holographic space from entanglement.
