Hawking-Moss transition with a black hole seed
Ruth Gregory, Ian G Moss, Naritaka Oshita +1
We extend the the concept of Hawking-Moss, or up-tunnelling, transitions in the early universe to include black hole seeds. The black hole greatly enhances the decay amplitude, how…
On catalyzed vacuum decay around a radiating black hole and the crisis of the electroweak vacuum
Takumi Hayashi, Kohei Kamada, Naritaka Oshita +1
False vacuum decay is a key feature in quantum field theories and exhibits a distinct signature in the early Universe cosmology. It has recently been suggested that the false vacuu…
Quantum Black Hole Seismology II: Applications to Astrophysical Black Holes
Naritaka Oshita, Daichi Tsuna, Niayesh Afshordi
With the advent of gravitational wave astronomy, searching for gravitational wave echoes from black holes (BHs) is becoming an interesting probe of their quantum nature near their…
Black Holes, Oscillating Instantons, and the Hawking-Moss transition
Ruth Gregory, Ian G. Moss, Naritaka Oshita
Static oscillating bounces in Schwarzschild de Sitter spacetime are investigated. The oscillating bounce with many oscillations gives a super-thick bubble wall, for which the total…
Small-mass naked singularities censored by the Higgs field
Naritaka Oshita
We investigate a vacuum decay around an over-spinning naked singularity by using the Israel junction condition. We found that if the Higgs field develops the second minimum at high…
Quantum Black Holes in the Sky
Jahed Abedi, Niayesh Afshordi, Naritaka Oshita +1
Black Holes are possibly the most enigmatic objects in our Universe. From their detection in gravitational waves upon their mergers, to their snapshot eating at the centres of gala…
Quantum Black Hole Seismology I: Echoes, Ergospheres, and Spectra
Naritaka Oshita, Daichi Tsuna, Niayesh Afshordi
Searches for gravitational wave echoes in the aftermath of mergers and/or formation of astrophysical black holes have recently opened a novel and surprising window into the quantum…
