On Field Theory Thermalization from Gravitational Collapse
David Garfinkle, Leopoldo A. Pando Zayas, Dori Reichmann
Motivated by its field theory interpretation, we study gravitational collapse of a minimally coupled massless scalar field in Einstein gravity with a negative cosmological constant…
Matters of Gravity, The Newsletter of the Topical Group on Gravitation of the American Physical Society, Volume 38, Fall 2011
David Garfinkle
GGR News: New version of LISA, by Karsten Danzmann We hear that, by David Garfinkle Research Briefs: Finally, results from Gravity Probe B, by Clifford M. Will Discovery of the hig…
Bertotti-Robinson and Melvin Spacetimes
David Garfinkle, E. N. Glass
Similarities between the Melvin and Bertotti-Robinson spacetimes are discussed and a uniqueness conjecture is formulated.
A positive energy theorem for Einstein-aether and Hořava gravity
David Garfinkle, Ted Jacobson
Energy positivity is established for a class of solutions to Einstein-aether theory and the IR limit of Hořava gravity within a certain range of coupling parameters. The class cons…
Rapid Thermalization in Field Theory from Gravitational Collapse
David Garfinkle, Leopoldo A. Pando Zayas
Motivated by the duality with thermalization in field theory, we study gravitational collapse of a minimally coupled massless scalar field in Einstein gravity with a negative cosmo…
How extreme are extreme black holes?
David Garfinkle
We examine the properties of nearly extremal black holes produced by gravitational collapse. It is shown that an observer who crosses the black hole horizon at late times rapidly e…
Non-Stationary Dark Energy Around a Black Hole
Ratindranath Akhoury, David Garfinkle, Ryo Saotome +1
Numerical simulations of the accretion of test scalar fields with non-standard kinetic terms (of the k-essence type) onto a Schwarzschild black hole are performed. We find a full d…
Gravitational collapse of k-essence
Ratindranath Akhoury, David Garfinkle, Ryo Saotome
We perform numerical simulations of the gravitational collapse of a k-essence scalar field. When the field is sufficiently strongly gravitating, a black hole forms. However, the bl…
