Abstract: Type II string theory has BPS
brane bound states that carry two charges. I will show that
their microcanonical ensemble average corresponds to a
spherical black hole mimicker, which possesses a long throat,
shares the same asymptotic data...
Abstract: Massive neutrinos suppress the growth
of cosmic structure on small, non-linear, scales. There is thus
much interest in using statistics beyond the power spectrum to
tighten constraints on the neutrino mass by extracting
additional...
Abstract: Black hole horizons have been a
mystery for more than a hundred years. What if they do not exist?
Black shells are horizonless black hole mimickers inspired by
string theory. The lecture introduces the physics of black shells
as well as...
Abstract: I will present the proof of a
conjectured relation between the energy-momentum tensor and the
displacement norm of superconformal defects. I will discuss
implications for the definition of an invariant tension
in Anti-de Sitter gravity...
Abstract: Compact stars, such as neutron stars
or white dwarfs, often collide with bigger, non-degenerate stars.
In this interaction, the NS captures copious amounts of matter that
flows inwards. The density of the gas in this scenario is so
high...
Abstract: Can we regularize chiral global
symmetries and their anomalies on a lattice with a finite
dimensional Hilbert space? We discuss how the vector and axial U(1)
symmetries of a massless Dirac fermion in 1+1d are realized in the
conventional...
