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…
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…
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…
