Holography and Black Hole
Vinay Malvimat
Research Professor
Research interest:
I investigate black holes from a quantum information perspective, employing the “island” formula to compute the entanglement entropy of Hawking radiation. This approach demonstrates unitarity restoration, reproduces the Page curve, and illuminates the multipartite and mixed-state entanglement structure of black hole radiation. Building on these findings, I seek to apply quantum information-theoretic measures to decoding protocols—such as the Hayden-Preskill model—to unveil hidden information in the radiation. Recent results also point to a possible connection between island phenomena and the emergence of gravitons, offering fresh insights into novel gravitational dynamics in quantum spacetime.
Byoungjoon Ahn
Research Professor
Research interest:
My research explores how quantum entanglement and holography address the black hole information paradox and explain the emergence of spacetime geometry. I am particularly interested in the dynamics of entanglement during black hole evaporation, the purification of mixed states, and the development of new approaches to quantifying multipartite entanglement.
Himanshu Parihar
Research Professor
Research interest:
My research lies at the intersection of quantum information theory, gauge/gravity duality and quantum gravity, with applications to the issue of black hole information loss. I have investigated various entanglement measures such as entanglement entropy, entanglement negativity, reflected entropy, and timelike entanglement entropy in AdS/CFT, AdS/BCFT and non-relativistic Lifshitz holography. These studies aim to illuminate how information-theoretic principles govern gravitational dynamics and the emergence of spacetime. My current research interests include quantum magic and quantum simulation. I am particularly interested in understanding how non-classical resources enable efficient quantum computation and simulation.
