Quantum radiation produced by the entanglement of quantum fields
Satoshi Iso, Naritaka Oshita, Rumi Tatsukawa +2
We investigate the quantum radiation produced by an Unruh-De Witt detector in a uniformly accelerating motion coupled to the vacuum fluctuations. Quantum radiation is nonvanishing,…
Resolution to the firewall paradox: The black hole information paradox and highly squeezed interior quantum fluctuations
Naritaka Oshita
Almheiri, Marolf, Polchinski, and Sully argued that, for a consistent black hole evaporation process, the horizon of a sufficiently old black hole should be replaced by a "firewall…
Unruh radiation produced by a uniformly accelerating charged particle in thermal random motions
Naritaka Oshita, Kazuhiro Yamamoto, Sen Zhang
In this study, we investigate the signature of the Unruh effect in quantum radiation from an accelerated charged particle interacting with vacuum fluctuations. Because a charged pa…
Entropic interpretation of the Hawking-Moss bounce
Naritaka Oshita, Jun'ichi Yokoyama
We revisit the derivation of the Hawking-Moss transition rate. Using the static coordinates, we show that the Euclidean action is entirely determined by the contribution of the ent…
Creation of an inflationary universe out of a black hole
Naritaka Oshita, Jun'ichi Yokoyama
We discuss a two-step mechanism to create a new inflationary domain beyond a wormhole throat which is created by a phase transition around an evaporating black hole. The first step…
