Bounding anisotropic Lorentz Invariance Violation from measurements of the effective energy scale of quantum gravity
Merce Guerrero, Anna Campoy-Ordaz, Robertus Potting +1
Observations of energy-dependent photon time delays from distant flaring sources provide significant constraints on Lorentz Invariance Violation (LIV). Such effects originate from…

The de Sitter swampland conjectures in the context of Chaplygin-inspired inflation
Orfeu Bertolami, Robertus Potting, Paulo M. Sá
In this work, we discuss the de Sitter swampland conjectures in the context of the generalized Chaplygin-inspired inflationary model. We demonstrate that these conjectures can be s…

A stable Lorentz-breaking model for an antisymmetric two-tensor
Robertus Potting
In this work we investigate possible actions for antisymmetric two-tensor field models subject to constraints that force the field to acquire a nonzero vacuum expectation value, th…
