Eddington-inspired-Born-Infeld tensorial instabilities neutralized in a quantum approach
Imanol Albarran, Mariam Bouhmadi-López, Che-Yu Chen +1
The recent direct detection of gravitational waves has highlighted the huge importance of the tensorial modes in any extended gravitational theory. One of the most appealing approa…
Annihilation-to-nothing: a quantum gravitational boundary condition for the Schwarzschild black hole
Mariam Bouhmadi-López, Suddhasattwa Brahma, Che-Yu Chen +2
The interior of a static Schwarzschild metric can be written in terms of two functions, similar to some models of anisotropic cosmology. With a suitable choice of canonical variabl…
Eikonal black hole ringings in generalized energy-momentum squared gravity
Che-Yu Chen, Pisin Chen
In the scope of black hole spectroscopy, several attempts have been made in the past decades in order to test black holes or gravitational theories via black hole quasinormal modes…
Separability of the Klein-Gordon equation for rotating spacetimes obtained from Newman-Janis algorithm
Che-Yu Chen, Pisin Chen
In the literature, the Newman-Janis algorithm (NJA) has been widely used to construct stationary and axisymmetric spacetimes to describe rotating black holes. In addition, it has b…
Primordial bouncing cosmology in the Deser-Woodard nonlocal gravity
Che-Yu Chen, Pisin Chen, Sohyun Park
The Deser-Woodard (DW) nonlocal gravity model has been proposed in order to describe the late-time acceleration of the universe without introducing dark energy. In this paper we fo…
Fuzzy Euclidean wormholes in the inflationary universe
Pisin Chen, Daeho Ro, Dong-han Yeom
In this paper, we investigate complex-valued Euclidean wormholes in the Starobinsky inflation. Due to the properties of the concave inflaton potential, the classicality condition a…
