de Sitter in String Theory vs. Gibbons & Hawking
Yoav Zigdon
This paper corroborates a statement that perturbative string theory does not admit a solution whose spacetime metric is de Sitter times a closed manifold, to all orders in the …

Bridging Worldsheet CFTs and Wormholes
Yoav Zigdon
I provide multiple examples of conformal field theories (CFTs) on the worldsheet that describe string propagation in target space wormholes connecting two disjoint asymptotic manif…

Superball of Strings
Yoav Zigdon
I solve the equations of the low-energy limit of string theory to obtain a solution corresponding to a microcanonical ensemble of highly-excited superstrings. This ``Superball of S…
