Categorical generalization of MacDowell Mansouri gravity coupled to Kalb Ramond fields
Miguel A. Oliveira
In this work we generalize the MacDowell-Mansouri theory of gravity using strict 2-groups. To achieve this, we construct the categorical generalization of the ISO(4,1) group, which…
Hamiltonian analysis of the BFCG formulation of General Relativity
Aleksandar Mikovic, Miguel A. Oliveira, Marko Vojinovic
We perform the complete Hamiltonian analysis of the BFCG action for General Relativity. We determine all the constraints of the theory and classify them into the first-class and th…
The Theory and Canonical Quantization of Gravity
Miguel Angelo Oliveira
This is a PhD thesis on a categorical generalization of the model called the theory. The new theory is equivalent to General Relativity at the classical level but, at t…
Hamiltonian analysis of the BFCG theory for a strict Lie 2-group
Aleksandar Mikovic, Miguel Angelo Oliveira, Marko Vojinovic
We perform a complete Hamiltonian analysis of the BFCG action for a general Lie 2-group by using the Dirac procedure. We show that the resulting dynamical constraints eliminate all…
Hamiltonian analysis of the BFCG theory for the Poincare 2-group
Aleksandar Mikovic, Miguel A. Oliveira, Marko Vojinovic
We perform the full Hamiltonian analysis of the topological BFCG action based on the Poincare 2-group. The Hamiltonian of the theory is constructed, and the algebra of constraints…
Canonical formulation of Poincare BFCG theory and its quantization
Aleksandar Mikovic, Miguel A. Oliveira
We find the canonical formulation of the Poincare BFCG theory in terms of the spatial 2-connection and its canonically conjugate momenta. We show that the Poincare BFCG action is d…
Velocity measurements in General Relativity revisited
Miguel A. Oliveira
In this work we generalize an earlier treatment of the measurements of velocities at the event horizon of a black hole. This is intended as a pedagogical exercise as well as one mo…
Spin-Orbit Coupling in Diamond and Zincblende Heterostructures
Miguel A Oliveira, Angus MacKinnon
Spin splittings in III-V materials and heterostructures are of interest because of potential applications, mainly in spintronic devices. A necessary condition for the existence of…
