Tunneling between single and multi-centered black hole configurations
Hyeyoun Chung
We find a gravitational instanton that connects an initial state corresponding to a single-centered extremal Reissner-Nordstrom (ERN) black hole configuration, to a final state cor…
Fragmentation of black hole scaling throats in N=2 supergravity
Hyeyoun Chung
We find an instanton analogous to the Brill instanton that describes the fragmentation of a single-centered black hole scaling throat of charge in N=2 supergravit…
Hawking Radiation and Entropy from Horizon Degrees of Freedom
Hyeyoun Chung
We study the thermodynamic properties of horizons using the dynamical description of the gravitational degrees of freedom at a horizon found in a previous work. We use the action o…
Dynamics of Diffeomorphism Degrees of Freedom at a Horizon
Hyeyoun Chung
We define a set of boundary conditions that ensure the presence of a null hypersurface with the essential characteristics of a horizon, using the formalism of weakly isolated horiz…
Asymptotic Symmetries of Rindler Space at the Horizon and Null Infinity
Hyeyoun Chung
We investigate the asymptotic symmetries of Rindler space at null infinity and at the event horizon using both systematic and ad hoc methods. We find that the approaches that yield…
