Dynamical breaking of symmetries beyond the standard model and supergeometry
Andrej B. Arbuzov, Diego Julio Cirilo-Lombardo
Group theoretical realizations containing the electroweak sector of the Standard Model are discussed from the supersymmetry point of view. Dynamical breaking of the symmetry is per…

Andrej B. Arbuzov, Diego Julio Cirilo-Lombardo
Nonlinear realizations of the SO(4,2) group are discussed from the point of view of symmetries. Dynamical symmetry breaking is introduced. One linear and one quadratic model in cur…
Peccei-Quinn Transformations and Black Holes : Orbit Transmutations and Entanglement Generation
Alessio Marrani, Thiago Prudencio, Diego J. Cirilo-Lombardo
In a recent paper [Mod. Phys. Lett. A30 (2015) 1550104], the black-hole/qubit correspondence (BHQC) was exploited to define "black hole quantum circuits" allowing for a change of t…
Relativistic dynamics, Green function and pseudodifferential operators
Diego Julio Cirilo-Lombardo
The central role played by pseudodifferential operators in relativistic dynamics is very well know. In this work, operators as the Schrodinger one (e.g: square root) are treated fr…

Fermion interactions, cosmological constant and spacetime dimensionality in an unified approach based on affine geometry
Diego Julio Cirilo-Lombardo, Salvatore Capozziello, Alexander Dorokhov
One of the main features of unified models, based on affine geometries, is that all possible interactions and fields naturally arise under the same standard. Here, we consider, fro…

At the classical level, redefinitions of the field content of a Lagrangian allow to rewrite an interacting model on a flat target space, in the form of a free field model (no poten…
