Well-posed non-vacuum solutions in Robinson--Trautman geometry
T. Tahamtan, D. Flores-Alfonso, O. Svitek
We study nonlinear matter models compatible with radiative Robinson--Trautman spacetimes and analyze their stability and well-posedness. The results lead us to formulate a conjectu…
Gravitational Waves from Thurston Geometries
Daniel Flores-Alfonso, Cesar S. Lopez-Monsalvo, Marco Maceda
It has been established that the famous three-dimensional Thurston geometries have four intrinsically Lorentzian analogs. We explore these spacetimes in three-dimensional general r…
Self duality in unconventional conformal supersymmetry
Pedro D. Alvarez, Cristóbal Corral, Jorge Zanelli
In this work, we study (anti-)self duality conditions in unconventional conformal supersymmetry. We focus on a theory constructed in a Townsend-MacDowell-Mansouri form for an $SU(2…
A note on the Hamiltonian structure of transgression forms
Pablo Pais, Patricio Salgado-Rebolledo, Aldo Vera
By incorporating two gauge connections, transgression forms provide a generalization of Chern-Simons actions that are genuinely gauge-invariant on bounded manifolds. In this work,…
Gravitating anisotropic merons and squashed spheres in the three-dimensional Einstein-Yang-Mills-Chern-Simons theory
Fabrizio Canfora, Cristóbal Corral
We construct the first analytic examples of self-gravitating anisotropic merons in the Einstein-Yang-Mills-Chern-Simons theory in three dimensions. The gauge field configurations h…
The geometry of induced currents in two dimensional media
Cesar S. Lopez-Monsalvo, Servando Vargas-Serdio, Julian A. Alzate-Cardenas +1
We present a framework that allows us to clearly identify the geometric features underlying the phenomenon of superconductivity in two dimensional materials. In particular, we show…
