Unraveling the Physical Meaning Behind Elko's Dual structure
Gabriel Brandão de Gracia, Rodolfo José Bueno Rogerio, Luca Fabbri
In this work, we shall analyze the necessity of a proper definition of the dual structure for Elko spinors, and singular spinors in general. We examine in detail why the Dirac dual…
Covariant operator formalism for higher derivative systems: Vector spin- dual model as a prelude to generalized QED
G. B. de Gracia, A. A. Nogueira
In this work we extend the Kugo-Ojima-Nakanishi covariant operator formalism to quantize two higher derivative systems, considering their extended phase space structures. More spec…
Duality as a Method to Derive a Gauge Invariant Massive Electrodynamics and New Interactions
G. B. de Gracia, B. M. Pimentel
Taking into account the recent developments associated with duality in physics, this article is focused on investigating the properties of a tensor generalization of the electrodyn…
Irreducible representations of the inhomogeneous Lorentz group with two-fold Wigner degeneracy
Dharam Vir Ahluwalia, G. B. de Gracia, Julio M. Hoff da Silva +2
Not all complete set of spinors can be used as expansion coefficients of a quantum field. In fact, Steven Weinberg established the uniqueness of Dirac spinors for this purpose prov…
On valley asymmetry in a topological interaction for quasi-particles
G. B. de Gracia, B. M. Pimentel, R. da Rocha
This paper is focused on investigating the effects of a statistical interaction for graphene-like systems, providing Haldane-like properties for topologically trivial lattices. The…
Fermionic dark matter interaction with the photon and the proton in the quantum field-theoretical approach and generalizations
G. B. de Gracia, R. da Rocha
Mass dimension one quantum fields, constructed upon eigenspinors of the charge conjugation operator with dual helicity (ELKO), are prime candidates to describe dark matter. Their i…
A Generalized Stueckelberg-Higgs gauge theories
C. A. Bonin, G. B. de Gracia, A. A. Nogueira +1
The aim of this work is to discuss and explore some generalized aspects of generation of photon mass respecting gauge symmetry. We introduce generalized Stueckelberg and Higgs gaug…
Simple prescription for computing the nonrelativistic interparticle potential energy related to dual models
G. B. de Gracia, G. P. de Brito
Following a procedure recently utilized by Accioly et al. to obtain the D-dimensional interparticle potential energy for electromagnetic models in the nonrelativistic limit, and re…
