Exponentially Long Evaporation of Noncommutative Black Hole
Pei-Ming Ho, Wei-Hsiang Shao, Takuya Yoda
We investigate Hawking radiation in noncommutative spacetime. For a dynamical black hole formed by the collapse of a matter shell, we demonstrate that spacetime noncommutativity mo…

Heat and work in black hole thermodynamics via holography
Tomohiro Shigemura, Keito Shimizu, Sotaro Sugishita +2
We propose a formulation of black hole thermodynamics that incorporates the notions of heat and work, based on the thermodynamics in quantum theory and the AdS/CFT correspondence.…

Complex Saddles of Truncated String Amplitudes
Takuya Yoda
String scattering amplitudes in the high energy asymptotic region have been studied by saddle point approximation. Recently, it was pointed out that infinitely many complex saddles…
