Abstract

In this talk, I will discuss the emergent factorization of Hilbert space in the low-energy description of matrix models and its implications for the black hole information paradox. I will explain the motivation of our work based on the black hole information paradox. Subsequently, I will present the collective description of the low-energy sector of the two classes of matrix models we consider--SU(N) matrix models and U(N) matrix models. The factorization of the Hilbert space in this effective low-energy sector leads us to examine the emergence of thermofield dynamics (TFD) state from a specific fine-tuned state of the original theory. Based on this toy model, I will make some comments on the recent progress in the black hole information paradox: black hole complementarity, the island conjecture and holography of information.
