Quantum Gravity via Causal Dynamical Triangulations
Causal dynamical triangulations (CDT ) represent a lattice regularization of the sum over spacetime histories, providing us with a nonperturbative formulation of quantum gravity. The ultravioletExpand
Unitarity of black hole evaporation in final-state projection models
A bstractAlmheiri et al. have emphasized that otherwise reasonable beliefs about black hole evaporation are incompatible with the monogamy of quantum entanglement, a general property of quantumExpand
The Spin-Foam Approach to Quantum Gravity
TLDR
The present status of the spin-foam approach to the quantization of gravity is reviewed and the pedagogical presentation of the recently-introduced new models for four-dimensional quantum gravity is paid to. Expand
Causal Topology in Future and Past Distinguishing Spacetimes
The causal structure of a strongly causal spacetime is particularly well endowed. Not only does it determine the conformal spacetime geometry when the spacetime dimension n >2, as shown by MalamentExpand
Introductory lectures to loop quantum gravity
We give a standard introduction to loop quantum gravity, from the ADM variables to spin network states. We include a discussion on quantum geometry on a fixed graph and its relation to a discreteExpand
Scalar curvature of a causal set.
TLDR
A one parameter family of retarded linear operators on scalar fields on causal sets is introduced that approximate square-(1/2)R where R is the Ricci scalar curvature and can be used to define an approximately local action functional for causal sets. Expand
Gravitational collapse and spacetime singularities
The nature of gravitational collapse was the subject of debate and controversy for much of the last century. During the 1960’s and 1970’s our understanding of general relativity consolidated andExpand
Causal sets: Discrete gravity
These are some notes in lieu of the lectures I was scheduled to give, but had to cancel at the last moment. In some places, they are more complete, in others much less so, regrettably. I hope they atExpand
Large N field theories, string theory and gravity
We describe the holographic correspondence between field theories and string/M theory, focusing on the relation between compactifications of string/M theory on Anti-de Sitter spaces and conformalExpand
