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…
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…
Temperatures of AdS black holes and holography revisited
Wontae Kim, Mungon Nam
In a dilaton gravity model, we revisit the calculation of the temperature of an evaporating black hole that is initially formed by a shock wave, taking into account the quantum bac…
