Characterization of Quantum Phase Transition using Holographic Entanglement Entropy

Understand

The entanglement exhibits extremal or singular behavior near quantum critical points (QCPs) in many condensed matter models.

• These intriguing phenomena, however, still call for a widely accepted understanding.
• In this letter we study this issue in holographic framework.
• We investigate the connection between the holographic entanglement entropy (HEE) and the quantum phase transition (QPT) in a lattice-deformed Einstein-Maxwell-Dilaton theory.
