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…
Cosmic Inflation From Regular Black Holes
Kensuke Sueto, Riku Yoshimoto, Pablo A. Cano
We study braneworld cosmology in quasi-topological gravity (QTG) with an infinite tower of higher-curvature terms, focusing on the case in which the bulk admits regular black hole…
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…
Hawking radiation in quantum Hall system with an expanding edge: application of anomaly method
Riku Yoshimoto, Yasusada Nambu
The relationship between gravitational anomalies and Hawking radiation of black holes was revealed by Wilczek and Robinson. In this study, we apply their method to an analogue de S…
