Retarded Green Function For Bopp--Podolsky Electrodynamics in Four-Dimensional De Sitter Spacetime
Wei Fan, Xiao Yan Chew
We study classical Bopp--Podolsky (BP) electrodynamics on four-dimensional de Sitter spacetime, focusing on its transverse retarded Green function and gauge-invariant electromagnet…
Scalarized Einstein-Euler-Heisenberg black holes at the approach to extremality
Hong Guo, Xiao Yan Chew, Yun Soo Myung
We investigate extremal black holes with scalar hair in the generic Einstein-Euler-Heisenberg (EEH)-scalar theory with two scalar couplings to the Maxwell term. One is an exponenti…
Dyonic Einstein-Maxwell-scalar black holes: the cold, the hot and the plunge
Shun Chen, Xiao Yan Chew, Jutta Kunz
We investigate dyonic nonlinearly scalarized black holes in Einstein-Maxwell-scalar theory. The domain of existence of scalarized dyonic black holes consists of three branches. The…
The simplest model of a scalarized black hole in the Einstein-Klein-Gordon theory
Xiao Yan Chew, Yun Soo Myung
We investigate scalarized black holes in the Einstein-minimally coupled scalar theory with a negative potential . The tachyonic instability is absent from analyzing t…
Hairy Reissner-Nordstrom Black Holes with Asymmetric Vacua
Xiao Yan Chew, Dong-han Yeom
We minimally coupled a scalar potential with asymmetric vacua to the Einstein gravity to numerically construct the hairy Reissner-Nordstrom black hole (RNBH) as a direct gen…
Yang-Mills instantons as the end point of black hole evaporation
Pisin Chen, Xiao Yan Chew, Misao Sasaki +1
Non-perturbative contributions of the Euclidean path integral are important to understand the information loss paradox. In this paper, we revisit the Yang-Mills instantons in the E…
Scalar Hairy Black Holes with Inverted Mexican Hat Potential
Xiao Yan Chew, Kok-Geng Lim
We numerically construct the asymptotically flat solutions of hairy black holes supported by a symmetric inverted Mexican hat potential with a local minimum and two degenerate glob…
Polar modes and isospectrality of Ellis-Bronnikov wormholes
Bahareh Azad, Jose Luis Blázquez-Salcedo, Xiao Yan Chew +2
We consider polar perturbations of static Ellis-Bronnikov wormholes and derive the coupled set of perturbation equations for the gravitational and the scalar field. For massless wo…
Non-Abelian Wormholes Threaded by a Yang-Mills-Higgs Field beyond the BPS Limit
Xiao Yan Chew, Kok-Geng Lim
We construct numerically the symmetric non-Abelian wormholes which are supported by a phantom field in the Einstein-Yang-Mills-Higgs theory beyond Bogomol'nyi-Prasad-Sommerfield (B…
Non--Abelian Wormholes Threaded by Yang--Mills--Higgs Field in the BPS Limit
Xiao Yan Chew, Kok-Geng Lim
In the Bogomol'nyi-Prasad-Sommerfield (BPS) limit of Einstein-Yang-Mills-Higgs theory, we construct numerically a non-Abelian wormhole supported by a phantom field. The probe limit…
Spinning Wormholes in Scalar-Tensor Theory
Xiao Yan Chew, Burkhard Kleihaus, Jutta Kunz
We consider spinning generalizations of the Ellis wormhole in scalar-tensor theory. Analogous to other compact objects these wormholes can carry a non-trivial scalarization. We det…
Geometry of Spinning Ellis Wormholes
Xiao Yan Chew, Burkhard Kleihaus, Jutta Kunz
We give a detailed account of the properties of spinning Ellis wormholes, supported by a phantom field. The general set of solutions depends on three parameters, associated with th…
