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…
The Effective Fluid Approach to Cosmological Nonlinearities: Applications to Preheating
Hyeyoun Chung
In [arXiv:1004.2488], Baumann et al. present a new formalism for studying cosmological systems where the characteristic scale of non-linearities is much smaller than the Hubble sca…
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…
