Lorentzian quantum cosmology from effective spin foams
Bianca Dittrich, José Padua-Argüelles
Effective spin foams provide the computationally most efficient spin foam models yet and are therefore ideally suited for applications e.g. to quantum cosmology. We provide here th…

Twisted geometries are area-metric geometries
Bianca Dittrich, José Padua-Argüelles
The quantum geometry arising in Loop Quantum Gravity has been known to semi-classically lead to generalizations of length-geometries. There have been several attempts to interpret…
