Closed String Cohomology in Open String Field Theory
Nicolas Moeller, Ivo Sachs
We show that closed string states in bosonic string field theory are encoded in the cyclic cohomology of cubic open string field theory (OSFT) which, in turn, classifies the deform…

Classical Stability of the BTZ Black Hole in Topologically Massive Gravity
Danny Birmingham, Susan Mokhtari, Ivo Sachs
We demonstrate the classical stability of the BTZ black hole within the context of topologically massive gravity. The linearized perturbation equations can be solved exactly in thi…

Finite Temperature Schwinger Model
Ivo Sachs, Andreas Wipf
The temperature dependence of the order parameter of the Schwinger model is calculated in the euclidean functional integral approach. For that we solve the model on a finite torus…
