Constructing the theory at the boundary, its dynamics and degrees of freedom
Irais Rubalcava-Garcia
Given a theory in a region of space-time with boundaries, defined by a Lagrangian, we propose a method to find the corresponding theory at the boundary (either space-like or time-l…
Actions, topological terms and boundaries in first order gravity: A review
Alejandro Corichi, Irais Rubalcava-Garcia, Tatjana Vukasinac
In this review we consider first order gravity in four dimensions. In particular, we focus our attention in formulations where the fundamental variables are a tetrad and a…
Energy in first order 2+1 gravity
Alejandro Corichi, Irais Rubalcava-Garcia
We consider =0 three dimensional gravity with asymptotically flat boundary conditions. This system was studied by Ashtekar and Varadarajan within the second order formalism -wit…
Hamiltonian and Noether charges in first order gravity
Alejandro Corichi, Irais Rubalcava-Garcia, Tatjana Vukasinac
We consider gravity in four dimensions in the vielbein formulation, where the fundamental variables are a tetrad and a SO(3,1) connection . We start with the most general ac…
The Jones vector as a spinor and its representation on the Poincaré sphere
G. F. Torres del Castillo, I. Rubalcava-Garcia
It is shown that the two complex Cartesian components of the electric field of a monochromatic electromagnetic plane wave, with a temporal and spatial dependence of the form ${\rm…
