Holography and Black Hole
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.
Sinong Liu
Research Professor
Research interest:
My research lies at the intersection of quantum information theory, non-equilibrium quantum dynamics, and gauge/gravity duality. I am interested in how entanglement and complexity characterise quantum dynamics far from equilibrium, and in how effective spacetime descriptions emerge from underlying quantum degrees of freedom in holographic and matrix-model settings. My recent work has focused on quantum quenches, spacelike singularities, and the role of complexity as a possible new entry in the holographic dictionary beyond 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.
Animik Ghosh
Research Professor
Research interest:
My research aims to explore how macroscopic physics emerges from a complex metamorphosis of underlying microscopic degrees of freedom. Within the context of holographic correspondence, I am interested in understanding the mechanism behind the emergence of non-trivial spacetimes from a large number of quantum mechanical degrees of freedom. Recently, I have also developed an interest towards using ideas in physics such as renormalization group and information theory to explain how neural networks learn.
