Higgs Mechanism for the Ashtekar Self-Dual Connection
Bruno Alexandre
We introduce the Higgs mechanism for the self-dual spin connection (also known as the Ashtekar connection), using the Plebański formulation of gravity. We develop our formalism wit…

Quantum Gravity Signatures in the Late-Universe
Michael W. Toomey, Savvas Koushiappas, Bruno Alexandre +1
We calculate deviations in cosmological observables as a function of parameters in a class of connection-based models of quantum gravity. In this theory non-trivial modifications t…

Possible quantum effects at the transition from cosmological deceleration to acceleration
Bruno Alexandre, Joao Magueijo
The recent transition from decelerated to accelerated expansion can be seen as a reflection (or "bounce") in the connection variable, defined by the inverse comoving Hubble length…
