Blackfolds as fluids and materials — •Niels Obers — Niels Bohr Institute, University of Copenhagen, Denmark

I will review the blackfold approach, which is an effective worldvolume theory capturing the dynamics of thin black branes. I will show how the method can be applied to construct, in the blackfold limit, numerous novel stationary, possibly charged, black holes in higher dimensions, both in vacuum gravity as well as supergravities. It furthermore provides insights into the dynamical stability of black objects under long wavelength perturbations. In particular, the approach shows that black branes possess both fluid as well as material properties, corresponding to intrinsic and extrinsic perturbations respectively, and I will discuss the associated response coefficients.
