Trade-off Relation for Black Hole Entropy Fluctuations
Kensuke Gallock-Yoshimura, Yoshihiko Hasegawa
Black holes respond to infalling quantum matter fields by changing their entropy. Since such matter is quantum in nature, the entropy response should be sensitive to its quantum fl…

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…
