Quantum black holes: inside and outside
Wei-Chen Lin, Dong-han Yeom, Dejan Stojkovic
For a unitary description of an evaporating black hole, one usually chooses the time slices that cover only outside of the event horizon, which is mostly problem-free because the e…
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…
Spacetime surgery for black hole fireworks
Wei-Chen Lin, Dong-han Yeom, Dejan Stojkovic
We construct an explicit model for the black hole to white hole transition (known as the black hole fireworks scenario) using the cut-and-paste technique. We model a black hole col…
