The concept of torsion in geometry, although known for a long time, has not gained
considerable attention from the physics community until relatively recently, due to its diverse …

Analogs of fundamental physical phenomena can be used in two ways. One way consists in
reproducing specific aspects of the classical or quantum gravity of quantum fields in curved …

Assuming dislocations could be meaningfully described by torsion, we propose here a
scenario based on the role of time in the low-energy regime of two-dimensional Dirac …

A bstract We construct a gauge theory based in the supergroup G= SU (2, 2| 2) that
generalizes MacDowell-Mansouri supergravity. This is done introducing an extended notion …

We propose two different high-energy-theory correspondences with graphene (and related
materials) scenarios, associated to grain boundaries, that are topological defects for which …

In supersymmetric extensions of the Standard Model, the observed particles come in fermion–
boson pairs necessary for the realization of supersymmetry (SUSY). In spite of the expected …

The counting of the degrees of freedom of the massless Rarita-Schwinger theory is revisited
using covariant and non-covariant techniques. The Ogievetsky-Sokatchev spin-block …

Counting the degrees of freedom of the massless Rarita-Schwinger theory is revisited using
Behrends-Fronsdal projectors. The identification of the gauge invariant part of the vector …

The Horndeski Lagrangian brings together all possible interactions between gravity and a
scalar field that yield second-order field equations in four-dimensional spacetime. As …

A bstract From a gauge SU (2, 2| 2) model with broken supersymmetry, we construct an
action for SU (2)× U (1) Yang-Mills theory coupled to gravity and matter in four dimensions …
