Holographic Schwinger-Keldysh effective action for heavy quarks in confinement and deconfinement phases
Shin Nakamura, Daichi Takeda
The holographic Schwinger-Keldysh (SK) prescription proposed by Skenderis and van Rees (SvR) has the advantage of being applicable whether or not the gravity dual contains a black…

A Lindbladian for holographic Brownian motion
Daichi Takeda
We derive a Lindbladian description of holographic Brownian motion in the high-temperature regime. Starting from the influence functional for a trailing string endpoint, we identif…

Black-hole formation and thermalization in open JT gravity
Ryo Adachi, Rumi Hasegawa, Takanori Ishii +1
Black-hole formation is expected, via holography, to correspond to thermalization in the boundary theory. For open quantum systems, an initial pure state generically evolves into a…
