Chiral vacuum fluctuations in quantum gravity
Joao Magueijo, Dionigi M. T. Benincasa
We examine tensor perturbations around a deSitter background within the framework of Ashtekar's variables and cousins parameterized by the Immirzi parameter . At the classical l…
Bimetric structure formation: non-Gaussian predictions
Joao Magueijo, Johannes Noller, Federico Piazza
The minimal bimetric theory employing a disformal transformation between matter and gravity metrics is known to produce exactly scale-invariant fluctuations. It has a purely equila…
Testing MOND/TEVES with LISA Pathfinder
Christian Trenkel, Steve Kemble, Neil Bevis +1
We suggest that LISA Pathfinder could be used to subject TEVES, and in particular the non-relativistic MOND phenomenology it incorporates, to a direct, controlled experimental test…
