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…

Complex saddles and time-delay of Veneziano amplitude
Takuya Yoda
String scattering amplitudes are typically expressed in formal integrals which diverge in physical kinematic regions. Recently the problem of divergence was cured by redefining int…
