3D Einstein action from 6D Kodaira-Spencer gravity
Johanna Erdmenger, Jonathan Karl, Jani Kastikainen +1
In view of embedding 3D gravity into topological string theory, we show that the dimensional reduction of 6D Kodaira-Spencer gravity on , i.e. the low-energ…
Topological Einstein gravity as Kodaira-Spencer gravity
Johanna Erdmenger, Jonathan Karl, Jani Kastikainen +2
As a contribution towards quantizing three-dimensional gravity, we show at the classical level that Euclidean three-dimensional Einstein gravity with a negative cosmological consta…
Modular theory and symmetry resolution in hyperfinite von Neumann algebras
Giuseppe Di Giulio, Moritz Dorband, Johanna Erdmenger +1
We study modular theory in hyperfinite von Neumann algebras, i.e. in those of type II or type III, from the viewpoint of a subregion charge sector decomposition. We address this sy…
On the Boundary Conformal Field Theory Approach to Symmetry-Resolved Entanglement
Giuseppe Di Giulio, René Meyer, Christian Northe +2
We study the symmetry resolution of the entanglement entropy of an interval in two-dimensional conformal field theories (CFTs), by relating the bipartition to the geometry of an an…
