Consistent discretizations as a road to quantum gravity
Rodolfo Gambini, Jorge Pullin
We present a brief description of the ``consistent discretization'' approach to classical and quantum general relativity. We exhibit a classical simple example to illustrate the ap…
Consistent discretization and canonical classical and quantum Regge calculus
Rodolfo Gambini, Jorge Pullin
We apply the ``consistent discretization'' technique to the Regge action for (Euclidean and Lorentzian) general relativity in arbitrary number of dimensions. The result is a well d…
Arbitrary black-string deformations in the black string-black hole transitions
Matthew Anderson, Luis Lehner, Jorge Pullin
We study the possible black string-black hole transition by analyzing the structure of the apparent horizon for a large family of time-symmetric initial data. We observe that, as j…
Fundamental gravitational limitations to quantum computing
Rodolfo Gambini, Rafael A. Porto, Jorge Pullin
Lloyd has considered the ultimate limitations physics places on quantum computers. He concludes in particular that for an ``ultimate laptop'' (a computer of one liter of volume and…
Classical and quantum general relativity: a new paradigm
Rodolfo Gambini, Jorge Pullin
We argue that recent developments in discretizations of classical and quantum gravity imply a new paradigm for doing research in these areas. The paradigm consists in discretizing…
Consistent discretizations: the Gowdy spacetimes
Rodolfo Gambini, Marcelo Ponce, Jorge Pullin
We apply the consistent discretization scheme to general relativity particularized to the Gowdy space-times. This is the first time the framework has been applied in detail in a no…
