S-Duality and Categorical Gauge Theory
Javier Chagoya, A. D. López-Hernández, M. Sabido
In this work, we revisit abelian S-duality in the context of higher gauge theory. By using a specific crossed module a set of transformations arise, which are known as the "thin" a…
Chern-Simons Inspired Massive Gravity
J. Chagoya, M. Sabido, A. Silva-García
In this work we propose a new 2+1 theory of gravity. We start with a modification of Chern-Simons 2+1 gravity. By introducing a vector field to the usual composition of the vie…
Categorical generalization of BF theory coupled to gravity
A. D. López-Hernández, Graciela Reyes-Ahumada, Javier Chagoya
We present a thorough introduction to the tools of category theory required for formulating gauge theories based on 2-connections. We provide a detailed construction of the categor…
BTZ entropy from topological M-theory
Javier Chagoya, Graciela Reyes-Ahumada, M. Sabido
By determining the relation between topological M-theory and the Chern-Simons actions for a gauge field constructed from the Lie algebra of either SL(2,R)x SL(2,R) or SL(2,C)x SL(2…
A new scalar-tensor realization of Hořava-Lifshitz gravity
Javier Chagoya, Gianmassimo Tasinato
We discuss a new covariant scalar-tensor system aimed to realise Hořava proposal for a power-counting renormalizable theory of gravity, with the special feature of not propagating…
Stealth configurations in vector-tensor theories of gravity
Javier Chagoya, Gianmassimo Tasinato
Studying the physics of compact objects in modified theories of gravity is important for understanding how future observations can test alternatives to General Relativity. We consi…
A geometrical approach to degenerate scalar-tensor theories
Javier Chagoya, Gianmassimo Tasinato
Degenerate scalar-tensor theories are recently proposed covariant theories of gravity coupled with a scalar field. Despite being characterised by higher order equations of motion,…
Black Holes and Abelian Symmetry Breaking
Javier Chagoya, Gustavo Niz, Gianmassimo Tasinato
Black hole configurations offer insights on the non-linear aspects of gravitational theories, and can suggest testable predictions for modifications of General Relativity. In this…
Galileon Higgs Vortices
Javier Chagoya, Gianmassimo Tasinato
Vortex solutions are topologically stable field configurations that can play an important role in condensed matter, field theory, and cosmology. We investigate vortex configuration…
Galileons and strong gravity
Javier Chagoya, Kazuya Koyama, Gustavo Niz +1
In the context of a cubic Galileon model in which the Vainshtein mechanism suppresses the scalar field interactions with matter, we study low-density stars with slow rotation and s…
Conformal Anisotropic Quantum Cosmology
J. F. Chagoya, M. Sabido
In this paper we apply the ideas put forward by Hořava, and introduce anisotropic transformations to cosmology. We start with the Kantowski-Sachs cosmological model and impose anis…
