Black holes in effective loop quantum gravity: Hawking radiation
Idrus Husin Belfaqih, Martin Bojowald, Suddhasattwa Brahma +1
Emergent modified gravity provides a covariant framework for holonomy effects in models of loop quantum gravity with consistent black hole solutions coupled to a scalar field. Seve…
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…
Perturbative emergent modified gravity on cosmological backgrounds: Kinematics
Martin Bojowald, Manuel Diaz, Erick I. Duque
Emergent modified gravity has shown that the canonical formulation of general relativity gives rise to a larger class of covariant modifications than action-based approaches, so fa…
Singularities in loop quantum cosmology
Martin Bojowald, Manuel Diaz, Erick I. Duque
Quantum effects are expected to modify the cosmological dynamics of the early universe while maintaining some (potentially discrete) notion of space-time structure. In one approach…
