G-algebroids: a unified framework for exceptional and generalised geometry, and Poisson-Lie duality
Mark Bugden, Ondrej Hulik, Fridrich Valach +1
We introduce the notion of G-algebroid, generalising both Lie and Courant algebroids, as well as the algebroids used in exceptional generalised geometr…
On the Conformal Symmetry of Exceptional Scalar Theories
Kara Farnsworth, Kurt Hinterbichler, Ondrej Hulik
The DBI and special galileon theories exhibit a conformal symmetry at unphysical values of the spacetime dimension. We find the Lagrangian form of this symmetry. The special confor…
Information recovery from pure state geometries in 3D
Ondrej Hulik, Joris Raeymaekers, Orestis Vasilakis
It is a well-studied phenomenon in AdS/CFT that pure states often appear 'too thermal' in the classical gravity limit, leading to a version of the information puzzle. One e…
Multi-centered higher spin solutions from conformal blocks
Ondrej Hulik, Joris Raeymaekers, Orestis Vasilakis
Motivated by the question of bulk localization in holography, we study the problem of constructing multi-centered solutions in higher spin gravity which describe point particles in…
