Unitary evolution of an evaporating black hole in canonical quantum gravity
Sijia Wang, Robert B. Mann, Dong-han Yeom
We propose a framework for understanding the information loss paradox in the context of canonical quantum gravity. We first revisit several approaches to black hole evaporation tha…
Acceleration in 3D Einstein-Gauss-Bonnet Gravity
Cendikiawan Suryaatmadja, Dong-han Yeom, Robert Mann
We present a new class of exact solutions in Einstein-Gauss-Bonnet gravity in 2+1 dimensions that generalize the C-metric. This set of metrics equals the C-metric multiplied by a f…
Quantum coherent dynamics of quasiclassical spacetimes
Sijia Wang, Achintya Sajeendran, Dong-han Yeom +2
In a wide range of quantum gravity theories, quasiclassical geometries, which are solutions to the Einstein field equations approximately, are described by "coherent states." Here…
Entanglement between pair-created twin universes with opposite time arrows should leave a birthmark on CMB spectrum
Pisin Chen, Kuan-Nan Lin, Wei-Chen Lin +1
Why (and how) the Universe was born is one of the ultimate questions in physics. Another big puzzle is about the arrow of time: why is there only one direction of time? Are these t…
A possible origin of the -vacuum as the initial state of the Universe
Pisin Chen, Kuan-Nan Lin, Wei-Chen Lin +1
We investigate the cosmological observables using the Euclidean path integral approach. Specifically, we study both the no-boundary compact instantons scenario and the Euclidean wo…
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…
