Bumpy horizons from non-linear sigma models
Fabrizio Canfora, Nicolás Grandi, Carla Henr\'ıquez-Báez +1
We show that black hole horizons with non-constant curvature can be constructed in any even dimension, when the source of the Einstein equations is given by the stress-energy tenso…
Viscoelastic and thermal response on nuclear pasta states at finite baryon density
Nicolás Grandi, Scarlett Rebolledo, Aldo Vera
We compute the viscoelastic and thermal response of non-homogeneous hadronic condensates at finite baryon density representing crystals of baryonic tubes and layers. We describe th…
A smooth road to bumpy horizons: shaping black holes with non-linear sigma models, from supergravity to higher dimensions
Fabrizio Canfora, Nicolás Grandi, Carla Henríquez-Báez +1
We construct new families of solutions for General Relativity coupled to a general class of non-linear sigma models, some of which can be embedded in supergravity. The solutions in…
Universality of the chiral soliton lattice and its interaction with quark matter
Fabrizio Canfora, Nicolás Grandi, Marcela Lagos +2
In this paper, we show that the chiral soliton lattice (ChSL) is, in a precise sense, a universal feature of the low-energy limit of QCD minimally coupled to Maxwell theory. Here,…
Holographic explorations of regular black holes in pure gravity
Monserrat Aguayo, Leonardo Gajardo, Nicolás Grandi +3
It has been recently established in \textit{Phys.Lett.B 861 (2025) 139260} that regular, asymptotically flat black holes exist in pure gravity theories in dimension greater than fo…
(Quasi-)normal modes of rotating black holes and new solitons in Einstein-Gauss-Bonnet
Lilianne Tapia, Monserrat Aguayo, Andrés Anabalón +5
In this paper, we analyze the scalar field (quasi-)normal modes of recently derived rotating black holes within the framework of Einstein-Gauss-Bonnet theory at the Chern-Simons po…
