The 2-Dimensional Dual of in AdS
Weichen Xiao, Ivo Sachs
We study the correlation functions of a conformally coupled -interacting theory in AdS and its dual CFT. The one-loop diagram is not expressible in terms of known tra…

Gravitational instantons from closed superstring field theory
Ivo Sachs, Xianghang Zhang
We test exact marginality of the deformation describing the resolution of a orbifold by analyzing the closed superstring equations of motion to third order in the si…

Probing of colliding wave spacetimes and a quantum Weyl conjecture
Ivo Sachs, Marc Schneider
We perform a quantum probing of colliding plane-wave space-times. In particular, we consider the Khan-Penrose and the Ferrari-Ibáñez solutions, which admit a strong and a weak si…
