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 sing…
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 tran…
Quantum Theory in AdS and its CFT Dual
Igor Bertan, Ivo Sachs, Evgeny D. Skvortsov
We compute the two- and four-point holographic correlation functions up to the second order in the coupling constant for a scalar theory in four-dimensional Euclidean anti-de…
Open-Closed String Correspondence in Open String Field Theory
Marco Baumgartl, Ivo Sachs
We address the problem of describing different closed string backgrounds in background independent open string field theory: A shift in the closed string background corresponds to…
