Late-time cosmic acceleration from quantum gravity
Daniele Oriti, Xiankai Pang
We deepen the analysis of the cosmological acceleration produced by quantum gravity dynamics in the formalism of group field theory condensate cosmology, treated at the coarse-grai…

Gravitational lensing of massive particles in Reissner-Nordström spacetime
Xiankai Pang, Junji Jia
In this work we study the deflection angle and gravitational lensing of both lightlike and timelike neutral rays in Reissner-Nordström (RN) spacetimes. The exact deflection an…
