In this talk I review the holographic dual of an entangled pair
of a quark and an anti-quark. The bulk dual on the Poincare patch
is a string with an Einstein-Rosen bridge on its worldsheet. String
solutions will be discussed that correspond to...
Solutions of string/M theory with low energy supersymmetry breaking
generically have light moduli fields whose masses are of order the
supersymmetry breaking scale. These fields -- whose expectation
values parametrise the size and shape of the...
Argyres-Douglas theories are four-dimensional N=2 SCFTs
characterized by the existence of mutually non-local massless BPS
states. The original examples of these theories were discovered
almost twenty years ago at special points of the Coulomb
branch...
I will review progress and questions originating from an attempt
to quantize pure gravity on AdS3 by using canonical quantization in
a "constrain first" approach. Questions will outnumber answers.
Conformal field theories (CFTs) defined at fixed points of
the
renormalization group flow can be lifted to curved space where they
develop
the well-known trace anomaly. In this talk we will consider the
trace
anomaly of CFTs with exactly marginal...
The LHC data are severely constraining natural theories of
electroweak symmetry breaking.
An important part of the constraints comes from the fact that
typically the partners of the top quark in carry color and can be
profusely produced at hadron...
Plasma-filled magnetospheres can extract energy from spinning
black holes and power a variety of observed astrophysical
phenomena. These magnetospheres are described by the highly
nonlinear equations of force-free electrodynamics, or FFE.
Typically...
