Non-invertible selection rules on heterotic non-Abelian orbifolds
Journal of High Energy PhysicsWe investigate coupling selection rules in heterotic string theory on non-Abelian orbifolds. Since boundary conditions on the orbifolds are classified by conjugacy classes of space group elements, non-Abelian orbifolds give rise to non-invertible ...

The bulk from the boundary; holography and AdS/CFT [PDF]
, 2008 In this thesis we consider various methods by which one can extract (in detail) the metric structure of asymptotically anti-de Sitter spacetime, using only information from the boundary.

Aspects of dark bubble cosmology from string theory [PDF]
This work investigates thoroughly a brane world scenario called "Dark Bubble Cosmology", which differs in crucial aspects from other proposals in string phenomenology: our four-dimensional universe rides an expanding bubble whose embedding naturally ...
