  • BTZ black hole with Korteweg–de Vries-type boundary conditions: thermodynamics revisited 

    Erices-Osorio, Cristián R.; Riquelme, Miguel; Rodríguez, Pablo (2019)
    The thermodynamic properties of the Bañados-Teitelboim-Zanelli black hole endowed with Korteweg–de Vries (KdV)-type boundary conditions are reconsidered. This family of boundary conditions is labeled by a non-negative ...

  • Cosmology in cubic and f(P) gravity 

    Erices-Osorio, Cristián R.; Papantonopoulos, Eleftherios; Saridakis, Emmanuel N. (2019)
    We construct cubic gravity and its f(P) extension and we investigate their early- and late-time cosmological applications. Cubic gravity is based on a particular invariant P, constructed from cubic contractions of the ...

  • EFT approach to black hole scalarization and its compatibility with cosmic evolution 

    Erices-Osorio, Cristián R.; Riquelme, Simón; Zalaquett, Nicolás (2022)
    We address the issue of black hole scalarization and its compatibility with cosmic inflation and big bang cosmology from an effective field theory (EFT) point of view. In practice, using a well-defined and healthy toy model ...

    Erices-Osorio, Cristián R.; Riquelme, Simón; Zalaquett, Nicolás (2023)
    We address the issue of black hole scalarization and its compatibility with cosmic inflation and Big Bang cosmology from an effective field theory (EFT) point of view. In practice, using a well-defined and healthy toy ...

  • Hairy black holes in disformal scalar-tensor gravity theories 

    Erices-Osorio, Cristián R.; Filis, Pantelis; Papantonopoulos, Eleftherios (2021)
    We show that the no-hair theorem for scalar-tensor theories with bimetric structure can be evaded. We find that hairy black hole solutions in the presence of an electric charge admit anti-de Sitter (AdS), flat or de Sitter ...

  • Stealth Ellis wormholes in Horndeski theories 

    Bakopoulos, Athanasios; Chatzifotis, Nikos; Erices-Osorio, Cristián R.; Papantonopoulos, Eleftherios (2023)
    In this work we are revisiting the well studied Ellis wormhole solution in a Horndeski theory motivated from the Kaluza-Klein compactification procedure of the more fundamental higher dimensional Lovelock gravity. We show ...
