Holographic Entanglement Entropy in the FLRW Universe
Toshifumi Noumi, Fumiya Sano, Yu-ki Suzuki
We compute a holographic entanglement entropy via Ryu--Takayanagi prescription in the three-dimensional Friedmann--Lemaître--Robertson--Walker universe. We consider two types of ho…

Cutoff Scale of Quadratic Gravity from Quantum Focusing Conjecture
Takamasa Kanai, Kengo Maeda, Toshifumi Noumi +1
We derive the cutoff length scale of the quadratic gravity in dimensional spacetime by demanding that the quantum focusing conjecture for the smeared quantum expansion h…

Gedanken Experiments to Destroy a Black Hole by a Test Particle: Multiply Charged Black Hole with Higher Derivative Corrections
Keisuke Izumi, Toshifumi Noumi, Daisuke Yoshida
We investigate a gedanken experiment to destroy an extremally charged black hole by dropping a test particle, provided that there are multiple gauge fields coupled with each…
