I will show how hydrodynamics is modified if the underlying
fluid constituents are massless Weyl fermions, which are anomalous
at the quantum level. Because of the non-dissipative nature of the
modification I will construct a partition function...
After a short introduction for non-experts to the LHC experiments,
we can talk about prospects for the next run. In its broadest form
the question open for discussion is whether we expect to discover
something in the next two to five years or not...
Understanding the language of holographic geometry is a
difficult problem. I propose a useful set of tools to supplement
our known bulk-to-boundary dictionary. These tools make use of
kinematic space, an integral transform of the bulk geometry,
and...
We study the quantum cosmology of a universe with conformal
matter. For homogeneous, isotropic metrics and matter, the quantum
gravitational path integral may be performed exactly. The result is
a "perfect bounce," in which the universe passes...
I present a solution to the electroweak hierarchy problem which
involves the relaxation of the Higgs mass in the early universe. I
will briefly discuss the limits of validity of the model as well as
potential experimental signatures.
In this talk I will describe the properties of half-BPS boundary
conditions in
three-dimensional N=4 gauge theories. I will discuss the
relationship between this work and the mathematical theory of
symplectic duality.
I will describe some situations where mysterious features have
appeared in numerical studies of the conformal bootstrap. It is
tempting to speculate that they may correspond to new CFTs, but we
do not yet have good guesses for a microscopic...
The relationship between 3d gravity and 2d CFT provides a useful
controlled playground in which to try and address issues of quantum
gravity. In this talk I describe recent thoughts about two related
problems: the construction of candidate duals to...
