Linearised Second Law for Higher Curvature Gravity and Non-Minimally Coupled Vector Fields
Aron C. Wall, Zihan Yan
Expanding the work of arXiv:1504.08040, we show that black holes obey a second law for linear perturbations to bifurcate Killing horizons, in any covariant higher curvature gravity…
Off-Shell Strings II: Black Hole Entropy
Amr Ahmadain, Aron C. Wall
In 1994, Susskind and Uglum argued that it is possible to derive the Bekenstein-Hawking entropy from string theory. In this article we explain the conceptual underpinnings…
Off-Shell Strings I: S-matrix and Action
Amr Ahmadain, Aron C. Wall
We explain why Tseytlin's off-shell formulation of string theory is well-defined. Although quantizing strings on an off-shell background requires an arbitrary choice of Weyl frame,…
Cauchy Slice Holography: A New AdS/CFT Dictionary
Goncalo Araujo-Regado, Rifath Khan, Aron C. Wall
We investigate a new approach to holography in asymptotically AdS spacetimes, in which time rather than space is the emergent dimension. By making a sufficiently large T^2-deformat…
Violation of Unitarity in Gravitational Subregions
Aron C. Wall
This essay contends that in quantum gravity, some spatial regions do not admit a unitary Hilbert space. Because the gravitational path integral spontaneously breaks CPT symmetry, "…
Holographic Tensor Networks in Full AdS/CFT
Ning Bao, Geoffrey Penington, Jonathan Sorce +1
We present a general procedure for constructing tensor networks for geometric states in the Anti-de Sitter/Conformal Field Theory (AdS/CFT) correspondence. Given a state in a large…
