PROBING UNIVERSAL FINGERPRINTS OF QUANTUM STATES: FROM QUANTUM ENTANGLEMENT TO CONFORMAL FIELD THEORY
Quantum many-body phases can exhibit universal properties originating from topology and symmetry, independent of microscopic details. Knowledge from other fields of physics, including quantum information and high-energy physics, provides new insights into unveiling such universal behaviors. In this dissertation, we develop the toolkits based on quantum entanglement and conformal field theory and apply them to quantum many-body phases. Specifically, we examine three typical systems: topological liquid, random Gaussian state, and critical spin chain. We demonstrate how the universal fingerprints can be probed using our toolkits, resulting in a new understanding of the topological, symmetric and conformal properties of quantum phases.
