Niels Bohr Institute Defines Black Hole States Using Thermal Correlators

Researchers at the Niels Bohr Institute and Nordita have defined a black hole state using a quantum spin chain model, calculating an effective central charge of approximately 5.2 for the entanglement entropy, which grows logarithmically with this central charge. By applying the Heisenberg model, the team offers an integrable system for investigating these phenomena, revealing a connection between condensed matter physics and the study of black holes. They also find evidence for thermalization at infinite temperature. This work builds upon the idea that at the heart of gauge-gravity duality lies a remarkable identification…
