Hamiltonian gravity with fermions
Erick I. Duque
Fermions are coupled to the Einstein-Cartan system in the canonical formulation, including the cosmological, the Barbero-Immirzi, and the non-minimal coupling constants. The result…
Hamiltonian gravity in tetrad-connection variables
Erick I. Duque
A systematic Hamiltonian formulation of the Einstein-Cartan system, based on the Hilbert-Palatini action with the Barbero-Immirzi and cosmological constants, is performed using the…
Emergent field theory
Erick I. Duque
The uniqueness theorems for general relativity and Yang-Mills theories can be circumvented by dropping the ubiquitous, yet often implicit, assumption that physical fields, such as…
Hawking evaporation and the fate of black holes in loop quantum gravity
Idrus Husin Belfaqih, Martin Bojowald, Suddhasattwa Brahma +1
A recent covariant formulation, that includes non-perturbative effects from loop quantum gravity (LQG) as self-consistent effective models, has revealed the possibility of non-sing…
Covariant LTB collapse in models of loop quantum gravity
Martin Bojowald, Erick I. Duque, Dennis Hartmann
Models of gravitational collapse provide important means to test whether non-classical space-time effects motivated for instance by quantum gravity can be realized in generic ways…
Lessons for loop quantum gravity from emergent modified gravity
Idrus Husin Belfaqih, Martin Bojowald, Suddhasattwa Brahma +1
Most of the potential physical effects of loop quantum gravity have been derived in effective models that modify the constraints of canonical general relativity in specific forms.…
