Robin boundary conditions in global AdS: exact double-trace thermodynamics and a soft-mode instability
David A. Lowe, Juanyi Yang
We consider a conformally coupled scalar field in four-dimensional global anti-de Sitter space with Robin boundary conditions, parametrized by an angle . On the boundary cylinde…
Conformally Invariant Corrections to the Anomaly-Induced Effective Action and Black Hole Evaporation in Four Dimensions
Bing-Nan Liu, David A. Lowe
When matter fields are integrated out in a large N approximation, the conformal anomaly induces an effective action up to conformally invariant correction terms. In the present wor…
Breakdown of Semiclassical Gravity in Four-Dimensional Black Hole Evaporation
David A. Lowe, Larus Thorlacius
We study black hole formation and evaporation in a four-dimensional semiclassical model that preserves diffeomorphism invariance and reproduces the one-loop trace anomaly. Solving…
Dynamical Black Hole Emission
David A. Lowe, Larus Thorlacius
Semiclassical black hole emission in four spacetime dimensions is studied using a non-local effective action. The field equations that determine the time-dependent renormalized str…
Generalized Effective Field Theory for Four-Dimensional Black Hole Evaporation
Bing-Nan Liu, David A. Lowe, Larus Thorlacius
The quantum induced stress tensor of 3+1-dimensional Einstein gravity, with conformally coupled matter, is studied in an effective field theory approach. In this context, Riegert's…
Effective Field Theory Description of Hawking Radiation
David A. Lowe, Larus Thorlacius
A study is made of Hawking radiation from four-dimensional black holes using effective field theory methods. The trace anomaly for the stress tensor in a general curved spacetime b…
Holographic Reconstruction of Gravitational Perturbations in AdS/CFT and Implications for Celestial Conformal Field Theory
David A. Lowe, Yiru Wang, Juanyi Yang
We begin by reexamining the holographic reconstruction of scalar fields in four-dimensional anti-de Sitter spacetime, adopting a purely Lorentzian signature derivation, reproducing…
Post AdS/CFT
David A. Lowe, Larus Thorlacius
The Hamiltonian governing the gravitational interaction of N relativistic particles in a four-dimensional anti-de Sitter background is derived to leading order in Newton's constant…
