A multi-axion model of inflation and dark matter
Marcos A. G. Garcia, Hansel Gordillo-Ruiz, Raul Henriquez-Ortiz +1
Models with extra dimensions include a tower of massive states that unavoidably contribute to cosmological dynamics. In particular, after compactification, a higher-dimensional axi…
Rolling with modular symmetry: quintessence and de Sitter in heterotic orbifolds
Hansel Gordillo-Ruiz, Miguel Hernandez-Segura, Ignacio Portillo-Castillo +2
Modular invariance is a fundamental symmetry in string compactifications, constraining both the structure of the effective theory and the dynamics of moduli and matter fields. It h…
The simplest case of dark inflaxion
Hansel Gordillo-Ruiz, Cesar Morales-Mena, Saul Ramos-Sanchez
Dark matter and cosmic inflation represent two of the major puzzles in cosmology. They are typically addressed by introducing separate fields with independent dynamics. On the othe…
