Weyl double copy in bimetric massive gravity
Hugo GarcÃa-Compeán, César I. Ramos
The Weyl double copy formalism, which relates the Weyl spinor with the square of the field strength, is studied in the context of Hassan-Rosen bigravity for stationary and time-dep…

Effects of quantum corrections to Lorentzian vacuum transitions in the presence of gravity
H. GarcÃa-Compeán, J. Hernández-Aguilar, D. Mata-Pacheco +1
We present a study of the vacuum transition probabilities taking into account quantum corrections. We first introduce a general method that expands previous works employing the Lor…

Scalar field inflation driven by a modification of the Heisenberg algebra
H. Garcia-Compean, D. Mata-Pacheco
We study the modifications induced on scalar field inflation produced by considering a general modification of the Heisenberg algebra. We proceed by modifying the Poisson brackets…
