String Theory seminar - Adam Bzowski [UNUSUAL DAY AND TIME: TUESDAY 12:00] Seminar

Abstract: I will argue that the Hilbert space of states of a holographic, traversable wormhole does not factorize into the tensor product of the boundary Hilbert spaces. I will analyze the scalar sector of the BTZ geon as an example. I will show that the number of peculiarities of the wormhole physics, such as null states and null operators, highly entangled vacuum states and the cross-boundary interactions, are all emerging as avatars of non-factorization. Finally, I will present a simple model where the non-factorization of the Hilbert space can be interpreted in terms of non-perturbative interactions.
