Spontaneous Hawking Radiation from Dynamical Black-Hole Formation in Quantum Spin Systems
Shunichiro Kinoshita, Keiju Murata, Daisuke Yamamoto +1
We show that Hawking radiation spontaneously generated by dynamical black-hole formation can be realized in a local quantum spin model. Starting from the ground state corresponding…
Refocusing of Wheeler--DeWitt wave functions at inner horizons
Takeshi Chiba, Keiju Murata, Daiki Saito
We study quantum gravitational effects inside hyperbolic black holes with both outer and inner horizons by solving the Wheeler--DeWitt (WDW) equation in the minisuperspace approxim…
Simulating Quantum Field Theories with Boundaries in Curved Spacetimes Using Open Spin Systems
Shunichiro Kinoshita, Keiju Murata, Daisuke Yamamoto +1
We develop a framework to simulate quantum field theories (QFTs) with boundaries in -dimenmsional curved spacetimes by employing open spin systems. Building upon our previou…
Singularity avoidance in black hole interiors by quantum gravity effects
Takeshi Chiba, Hiroki Matsui, Keiju Murata
The quantum nature of the Schwarzschild black hole interior is investigated through the Wheeler-DeWitt (WDW) equation. The interior of a static, spherically symmetric black hole is…
Operator dependence and robustness of spacetime-localized response in a quantum critical spin chain
Daichi Imagawa, Keiju Murata, Daisuke Yamamoto
We investigate the phenomenon of spacetime-localized response in a quantum critical spin system, with particular attention to how it depends on the spatial profile and operator con…
Kaluza-Klein monopole with scalar multiplet hair
Takaaki Ishii, Keiju Murata, Keita Sugawara
We construct Kaluza-Klein monopole solutions with scalar hair provied by a massive complex scalar field multiplet that minimally couples to five-dimensional Einstein gravity. Writi…
