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…
On the robustness of the chiral soliton lattice and the propagation of test quarks
Fabrizio Canfora, Nicolás Grandi, Marcela Lagos +2
In this paper, we demonstrate the robustness of the chiral soliton lattice (ChSL) against a specific class of operators: the higher-order corrections in the 't Hooft large- ex…
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…
Existence of a supersymmetric extension of the gauged non-linear -model and the transition from integrability to chaos
Fabrizio Canfora, Nicolás Grandi, Marcelo Oyarzo
The non-linear -Model minimally coupled with Maxwell theory in dimensions possesses a topologically non-trivial sector characterized by ``lasagna''-like configurations. We…
De Sitter geometric inflation from dynamical singularities
Adolfo Cisterna, Nicolas Grandi, Julio Oliva
Within the framework of geometric inflation, where the Friedmann equation is modified to incorporate an infinite series of higher curvature corrections, we describe the emergence o…
Exact oscillations and chaos on a non-Abelian coil
Fabrizio Canfora, Nicolas Grandi, Marcelo Oyarzo +1
We construct new exact solutions of the Georgi-Glashow model in dimensions. These configurations are periodic in time but lead to a stationary energy density and no energy fl…
-curvature and gravity
M. Chernicoff, G. Giribet, N. E. Grandi +2
In this paper, we consider a family of -dimensional, higher-curvature theories of gravity whose action is given by a series of dimensionally extended conformal invariants. The l…
Fermionic spectral functions in backreacting p-wave superconductors at finite temperature
G. L. Giordano, N. E. Grandi, A. R. Lugo
We investigate the spectral function of fermions in a -wave superconducting state, at finite both temperature and gravitational coupling, using the correspondence and…
Low energy electron-phonon effective action from symmetry analysis
D. C. Cabra, N. E. Grandi, G. A. Silva +1
Based on a detailed symmetry analysis, we state the general rules to build up the effective low energy field theory describing a system of electrons weakly interacting with the lat…
Chern-Simons action in noncommutative space
N. Grandi, G. A. Silva
We derive the noncommutative Chern-Simons action induced by Dirac fermions coupled to a background gauge field, for the fundamental, antifundamental, and the adjoint representation…
Non-BPS Dyons and Branes in the Dirac-Born-Infeld Theory
H. R. Christiansen, N. Grandi, F. A. Schaposnik +1
Non-BPS dyon solutions to D3-brane actions are constructed when one or more scalar fields describing transverse fluctuations of the brane, are considered. The picture emerging from…
Monopoles, Dyons and Theta Term in Dirac-Born-Infeld Theory
N. Grandi, R. L. Pakman, F. A. Schaposnik +1
We present dyon solutions to an SU(2) Dirac-Born-Infeld (DBI) gauge theory coupled to a Higgs triplet. We consider different non-Abelian extensions of the DBI action and study the…
