Quantum Charged Spinning Massless Particles in 2+1 dimensions
Ivan Morales, Bruno Neves, Zui Oporto +1
Motivated by the conduction properties of graphene discovered and studied in the last decades, we consider the quantum dynamics of a massless, charged, spin 1/2 relativistic partic…
A topological-like gravity model in a four dimensional space-time
Bruno Neves
In this work we consider a model for gravity in 4-dimensional space-time originally proposed by A. Chamseddine which may be derived by a 5-dimensional Chern-Simons theory. Its topo…
Behaviour of Charged Spinning Massless Particles
Ivan Morales, Bruno Neves, Zui Oporto +1
We revisit the classical theory of a relativistic massless charged point particle with spin and interacting with an external electromagnetic field. In particular, we give a proper…
Chern-Simons Gravity in Four Dimensions
Ivan Morales, Bruno Neves, Zui Oporto +1
Five dimensional Chern-Simons theory with (anti-)de Sitter SO(1,5) or SO(2,4) gauge invariance presents an alternative to General Relativity with cosmological constant. We consider…
Dimensionally compactified Chern-Simon theory in 5D as a gravitation theory in 4D
Ivan Morales, Bruno Neves, Zui Oporto +1
We propose a gravitation theory in 4 dimensional space-time obtained by compacting to 4 dimensions the five dimensional topological Chern-Simons theory with the gauge group SO(1,5)…
A Topological-like Model for Gravity in 4D Space-time
Ivan Morales, Bruno Neves, Zui Oporto +1
In this paper we consider a model for gravity in 4-dimensional space-time originally proposed by Chamseddine, which may be derived by dimensional reduction and truncation from a 5-…
