Gravitational Vacuum Condensate Stars in the Effective Theory of Gravity
Emil Mottola
The low energy effective theory of gravity comprises two elements of quantum theory joined to classical general relativity. The first is the quantum conformal anomaly, which is res…
Quantum Effects of the Conformal Anomaly in a 2D Model of Gravitational Collapse
Emil Mottola, Mani Chandra, Gian Mario Manca +1
The macroscopic effects of the quantum conformal anomaly are evaluated in a simplified two-dimensional model of gravitational collapse. The effective action and stress tensor of th…
Gravitational Vacuum Condensate Stars
Emil Mottola
Gravitational vacuum condensate stars, proposed as the endpoint of gravitational collapse consistent with quantum theory, are reviewed. Gravastars are cold, low entropy, maximally…
Beyond Einstein's Horizon: Gravitational Condensates and Black Hole Interiors in the Effective Theory of Gravity
Emil Mottola
Two of the most fundamental problems at the nexus of Einstein's classical General Relativity (GR) and Quantum Field Theory (QFT) are: (1) complete gravitational collapse, presumed…
Slowly rotating gravastars
Philip Beltracchi, Paolo Gondolo, Emil Mottola
We solve Einstein's equations for slowly-rotating gravitational condensate stars (gravastars) up to second order in the rotation by expanding about the spherically symmetric gravas…
Surface Stress Tensor and Junction Conditions on a Rotating Null Horizon
Philip Beltracchi, Paolo Gondolo, Emil Mottola
The general form of the surface stress tensor of an infinitesimally thin shell located on a rotating null horizon is derived, when different interior and exterior geometries are jo…
