Lorentzian Vacuum Transitions in gravity
H. García-Compeán, J. Hernández-Aguilar, D. Mata-Pacheco +1
We study Lorentzian vacuum transition probabilities between two minima of a scalar field potential within the framework of gravity. The analysis extends the previously consi…
Cosmological implications from some proposals in Quantum Gravity
D. Mata-Pacheco
In this thesis we present the cosmological applications of some proposals from Quantum Gravity. Namely, we will explore classical and quantum cosmological implications of the Gener…
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…
Hořava-Lifshitz theories and the Swampland
H. Garcia-Compean, D. Mata-Pacheco, L. Zapata
The compatibility between the de Sitter Swampland conjecture and Hořava--Lifshitz theories with a flat FLRW metric is studied. We first study the standard theor…
Lorentzian Vacuum Transitions with a Generalized Uncertainty Principle
H. Garcia-Compean, D. Mata-Pacheco
The vacuum transition probabilities between to minima of a scalar field potential in the presence of gravity are studied using the Wentzel-Kramers-Brillouin approximation. First we…
Generalized Uncertainty Principle effects in the Hořava-Lifshitz quantum theory of gravity
H. Garcia-Compean, D. Mata-Pacheco
The Wheeler-DeWitt equation for a Kantowski-Sachs metric in Hořava-Lifshitz gravity with a set of coordinates in minisuperspace that obey a generalized uncertainty principle is stu…
Lorentzian Vacuum Transitions in Hořava-Lifshitz Gravity
H. Garcia-Compean, D. Mata-Pacheco
The vacuum transition probabilities for a Friedmann-Lemaître-Robertson-Walker universe with positive curvature in Hořava-Lifshitz gravity in the presence of a scalar field potentia…
Lorentzian Vacuum Transitions for Anisotropic Universes
H. García-Compeán, D. Mata-Pacheco
The vacuum transition probabilities for anisotropic universes in the presence of a scalar field potential in the Wentzel-Kramers-Brillouin approximation are studied. We follow the…
BTZ quasinormal frequencies as poles of Green's function
A. Lopez-Ortega, D. Mata-Pacheco
Based on the well known fact that the quasinormal frequencies are the poles of the frequency domain Green's function we describe a method that allows us to calculate exactly the qu…
