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…
Semiclassical decay of de Sitter space into black holes with vortex-deformed horizons
Andrés Gomberoff, Carla HenrÃquez-Baez, Aldo Vera
We study the decay of de Sitter space into black holes whose horizons are dressed by BPS vortices of a action. The process is mediated by a regular Euclidean instan…
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,…
Self-gravitating baryonic tubes supported by - and -mesons and its flat limit
Gonzalo Barriga, Carla HenrÃquez-Baez, Leonardo Sanhueza +1
In this paper, we construct self-gravitating topological solitons in the Einstein non-linear sigma model coupled to -vector mesons in four space-time dimensions. These…
Exact black holes and black branes with bumpy horizons supported by superfluid pions
Fabrizio Canfora, Andrés Gomberoff, Carla HenrÃquez-Baez +1
We present exact solutions of the Einstein non-linear sigma model in spacetime dimensions, describing bumpy black holes and black branes. Using an Ansatz for superflu…
Universal self-gravitating skyrmions
Aldo Vera
The self-gravitating skyrmion is an exact solution of the Einstein -Skyrme model describing a topological soliton with baryon number , living in a -dimensional space…
