Squeezed quantum states and partner modes in the moving mirror model of black hole evaporation
Kuan-Nan Lin, Pisin Chen, Michael R. R. Good +1
The standard moving mirror model in (1+1)-dimensional spacetime is known to reproduce several quantum aspects of black hole evaporation. A perfectly reflecting, accelerating mirror…
Energy Flux as an Entanglement Current in Moving-Mirror Radiation
Yasusada Nambu, Riku Yoshimoto
In this work, we investigate the quantum entanglement properties of analog Hawking radiation produced by a moving mirror. Using two detector modes defined through window functions…
Entanglement Harvesting from Quantum Field: Insights via the Partner Formula
Yuki Osawa, Yasusada Nambu, Riku Yoshimoto
We examine the condition necessary for extracting entanglement from a quantum field through the use of two local modes A and B (detector modes). We show that Simon's entanglement c…
Acceleration-induced radiation from a qudit particle detector model
Kensuke Gallock-Yoshimura, Yuki Osawa, Yasusada Nambu
We nonperturbatively examine the emission rate of acceleration-induced radiation from a uniformly accelerated gapless qudit-type Unruh-DeWitt detector. We find that the emission ra…
Stochastic inflation and entropy bound in de Sitter spacetime
Hiromasa Tajima, Yasusada Nambu
We investigate the entropy dynamics of de Sitter spacetime during the inflationary phase. The cosmological horizon in de Sitter spacetime, which limits the causally accessible regi…
Gravitational entanglement witness through Einstein ring image
Youka Kaku, Yasusada Nambu
We investigate the interplay between quantum theory and gravity by exploring gravitational lensing and Einstein ring images in a weak gravitational field induced by a mass source i…
