A First Analysis of Stochastic Composite Gravity
Joshua Erlich
We present a first analysis of a nonperturbative approach to quantum gravity based on a representation of quantum field theory in terms of stochastic processes. The stochastic desc…
Background-Independent Composite Gravity
Austin J. Batz, Joshua Erlich, Luke Mrini
We explore a background-independent theory of composite gravity. The vacuum expectation value of the composite metric satisfies Einstein's equations (with corrections) as a consist…
Stochastic Emergent Quantum Gravity
Joshua Erlich
We present a stochastic framework for emergent quantum gravity coupled to matter. The Hamiltonian constraint in diffeomorphism-invariant theories demands the identification of a cl…
The Cosmological Constant Problem in Brane--Worlds and Gravitational Lorentz Violations
C. Csaki, J. Erlich, C. Grojean
Brane worlds are theories with extra spatial dimensions in which ordinary matter is localized on a (3+1) dimensional submanifold. Such theories could have interesting consequences…
