Electric Time in Quantum Cosmology
Stephon Alexander, Martin Bojowald, Antonino Marciano +1
Effective quantum cosmology is formulated with a realistic global internal time given by the electric vector potential. New possibilities for the quantum behavior of space-time are…
Horava-Lifshitz theory as a Fermionic Aether in Ashtekar gravity
Stephon Alexander, Joao Magueijo, Antonino Marciano
We show how Hořava-Lifshitz (HL) theory appears naturally in the Ashtekar formulation of relativity if one postulates the existence of a fermionic field playing the role of aether.…
The Hidden Quantum Groups Symmetry of Super-renormalizable Gravity
Stephon Alexander, Antonino Marciano, Leonardo Modesto
In this paper we consider the relation between the super-renormalizable theories of quantum gravity (SRQG) studied in [arXiv:1110.5249v2, arXiv:1202.0008] and an underlying non-com…
