Inflationary tensor fluctuations, as viewed by Ashtekar variables and their imaginary friends
Laura Bethke, Joao Magueijo
We investigate tensor modes in inflationary scenarios from the point of view of Ashtekar variables and their generalizations labelled by Immirzi parameter γ, which we'll assume ima…

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…
