Bag-of-gold spacetimes, Euclidean wormholes, and inflation from domain walls in AdS/CFT
Zicao Fu, Donald Marolf
We use Euclidean path integrals to explore the set of bulk asymptotically AdS spacetimes with good CFT duals. We consider simple bottom-up models of bulk physics defined by Einstei…
Traversable Asymptotically Flat Wormholes with Short Transit Times
Zicao Fu, Brianna Grado-White, Donald Marolf
We construct traversable wormholes by starting with simple four-dimensional classical solutions respecting the null energy condition and containing a pair of oppositely charged bla…
A perturbative perspective on self-supporting wormholes
Zicao Fu, Brianna Grado-White, Donald Marolf
We describe a class of wormholes that generically become traversable after incorporating gravitational back-reaction from linear quantum fields satisfying appropriate (periodic or…
Causal holographic information does not satisfy the linearized quantum focusing condition
Zicao Fu, Donald Marolf, Marvin Qi
The Hubeny-Rangamani causal holographic information (CHI) defined by a region of a holographic quantum field theory (QFT) is a modern version of the idea that the area of event…
Holographic complexity is nonlocal
Zicao Fu, Alexander Maloney, Donald Marolf +2
We study the "complexity equals volume" (CV) and "complexity equals action" (CA) conjectures by examining moments of of time symmetry for wormholes having asymptoti…
Bare Quantum Null Energy Condition
Zicao Fu, Donald Marolf
The quantum null energy condition (QNEC) is a conjectured relation between a null version of quantum field theory energy and derivatives of quantum field theory von Neumann entropy…
The Quantum Null Energy Condition in Curved Space
Zicao Fu, Jason Koeller, Donald Marolf
The quantum null energy condition (QNEC) is a conjectured bound on components ) of the stress tensor along a null vector at a point in terms of…
Violating the Quantum Focusing Conjecture and Quantum Covariant Entropy Bound in dimensions
Zicao Fu, Jason Koeller, Donald Marolf
We study the Quantum Focussing Conjecture (QFC) in curved spacetime. Noting that quantum corrections from integrating out massive fields generally induce a Gauss-Bonnet term, we st…
Time-independent wormholes
Zicao Fu, Donald Marolf, Eric Mefford
We study two-sided static wormholes with an exact Killing symmetry that translates both mouths of the wormhole toward the future. This differs from the familiar Kruskal wormhole wh…
Does horizon entropy satisfy a Quantum Null Energy Conjecture?
Zicao Fu, Donald Marolf
A modern version of the idea that the area of event horizons gives times an entropy is the Hubeny-Rangamani Causal Holographic Information (CHI) proposal for holographic field…
A coarse-grained generalized second law for holographic conformal field theories
William Bunting, Zicao Fu, Donald Marolf
We consider the universal sector of a -dimensional large- strongly-interacting holographic CFT on a black hole spacetime background . When our CFT is coupled to dynami…
