Euclidean teleparallel relativity and black hole partition functions
Jose Beltrán Jiménez, Tomi S. Koivisto
The Euclidean path integral approach to quantum gravity is conventionally formulated in terms of the Einstein-Hilbert-York-Gibbons-Hawking action, which requires suitable subtracti…
On Evidence for Elastic Interactions in the Dark Sector
Jose Beltrán Jiménez, Dario Bettoni, David Figueruelo +1
The increasing quality of cosmological data has revealed some tensions that could be signalling the necessity of incorporating new physics into our cosmological model. One particul…
Resilience of DBI screened objects and their ladder symmetries
Jose Beltrán Jiménez, Dario Bettoni, Philippe Brax
Scalar field theories with a shift symmetry come equipped with the -mouflage (or kinetic screening) mechanism that suppresses the scalar interaction between massive objects belo…
A class of ghost-free theories in symmetric teleparallel geometry
Antonio G. Bello-Morales, Jose Beltrán Jiménez, Alejandro Jiménez Cano +2
Theories formulated in the arena of teleparallel geometries are generically plagued by ghost-like instabilities or other pathologies that are ultimately caused by the breaking of s…
On the (non-)degeneracy of massive neutrinos and elastic interactions in the dark sector
Jose Beltrán Jiménez, David Figueruelo, Florencia Anabella Teppa Pannia
Cosmological models featuring an elastic interaction in the dark sector at linear order has been shown to provide a promising scenario for alleviating the tension. A natural…
