Investigation of the black-hole quantum atmosphere from the effective proper temperature
Sojeong Cheong, Wontae Kim
Hawking radiation may be regarded as originating at the event horizon; however, its spatial origin can instead be distributed over a finite region outside the horizon. In this pape…
Gauss-Bonnet scalarization of charged qOS-black holes
Hong Guo, Wontae Kim, Yun Soo Myung
The Gauss-Bonnet (GB) scalarization for charged quantum Oppenheimer-Snyder (cqOS)-black holes is investigated in the Einstein-Gauss-Bonnet-scalar theory with the nonlinear electrod…
Extended symmetry of the Maxwell theory with a gauge coupling constant as a conserved charge
Sojeong Cheong, Myungseok Eune, Wontae Kim +1
It has been proposed that any coupling constant in a covariant action can be treated as a conserved charge by promoting the coupling constant to auxiliary fields, typically realize…
Gravitational constant as a conserved charge in black hole thermodynamics
Wontae Kim, Mungon Nam
Recent work has shown that couplings multiplying individual terms in a Lagrangian can be promoted to conserved charges by introducing scalar-gauge pairs. The gravitational constant…
Strong gravitational lensing effects of black holes with quantum hair
Sojeong Cheong, Wontae Kim
According to the no-hair theorem, stationary black holes are uniquely characterized by their mass, charge, and angular momentum. In this paper, we explore quantum hair by deriving…
Einstein ring of dust shells with quantum hair
Sojeong Cheong, Wontae Kim, Mungon Nam
The information about the internal structure of a compact object is classically inaccessible to external observers. In this paper, we investigate how quantum corrections to gravita…
Validity of black hole complementarity in an accelerating Schwarzschild black hole
Wontae Kim, Mungon Nam
Black hole complementarity has been well understood in spherically symmetric black holes. To study its validity for an accelerating Schwarzschild black hole, which has a preferred…
The quasilocal energy and thermodynamic first law in accelerating AdS black holes
Wontae Kim, Mungon Nam, Sang-Heon Yi
We scrutinize the conserved energy of an accelerating AdS black hole by employing the off-shell quasilocal formalism, which amalgamates the ADT formalism with the covariant phase s…
Quantum geodesics reflecting the internal structure of stars composed of shells
Sojeong Cheong, Wontae Kim
In general relativity, an external observer cannot distinguish distinct internal structures between two spherically symmetric stars that have the same total mass . However, when…
Investigation of black hole complementarity in AdS black holes
Wontae Kim, Mungon Nam
Black hole complementarity plays a pivotal role in resolving the information loss paradox by treating Hawking radiation as carriers of information, apart from the complicated mecha…
