The Flavor of Non-Abelian Orbifolds
Miguel Hernandez-Segura, Xiang-Gan Liu, Ricardo Perez-Martinez +1
In string model building, flavor symmetries can arise from the geometric features of the compactification space. In the case of heterotic orbifold models, modular and traditional f…

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…

Non-Abelian orbifolds of the SO(32) heterotic string
Miguel Hernandez-Segura, Saul Ramos-Sanchez
Non-Abelian toroidal heterotic orbifolds have received comparatively little attention, mainly because of the significant computational challenges they pose, even at the level of co…
