Detector Based Evaluation of Extractable Entanglement in Flat spacetime
Hiromasa Tajima, Riku Yoshimoto, Ryo Nemoto +1
Entanglement entropy (EE) is widely used to quantify quantum correlations in field theory, with the well-known result in two-dimensional conformal field theory (CFT) predicting a l…

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…
