A bstract After turning on an interaction that couples the two boundaries of an eternal BTZ
black hole, we find a quantum matter stress tensor with negative average null energy, whose …

We study various aspects of wormholes that are made traversable by an interaction beween
the two asymptotic boundaries. We concentrate on the case of nearly‐gravity and discuss a …

A bstract In this paper, we study the dynamics of end-of-the-world (EOW) branes in AdS with
scalar fields localized on the branes as a new class of gravity duals of CFTs on manifolds …

A bstract Holography has taught us that spacetime is emergent and its properties depend on
the entanglement structure of the dual theory. In this paper, we describe how changes in the …

We introduce a new quantity, called pseudo-entropy, as a generalization of entanglement
entropy via postselection. We expect this quantity to provide a new class of order parameters …

A bstract We consider spacetime initiated by a finite-sized initial boundary as a
generalization of the Hartle-Hawking no-boundary state. We study entanglement entropy of …

The black hole singularity plays a crucial role in formulating Hawking's information paradox.
The global spacetime analysis may be reconciled with unitarity by imposing a final state …

Quantum gravity may have as much to tell us about the foundations and interpretation of
quantum mechanics as it does about gravity. The Copenhagen interpretation of quantum …

A bstract According to holography, entanglement is the building block of spacetime;
therefore, drastic changes of entanglement will lead to interesting transitions in the dual …

A bstract We systematically study moving mirror models in two-dimensional conformal field
theory (CFT). By focusing on their late-time behavior, we separate the mirror profiles into four …
