Six dimensional superconformal quantum field theories are in
between the most interesting quantum systems whose existence is
guaranteed by stringy arguments. In this seminar I am going to
discuss some aspects of their geometric engineering using F...
The existence and stability of atoms relies on the fact that
neutrons are more massive than protons. The mass difference is only
0.14% of the average. This tiny mass splitting has significant
astrophysical and cosmological implications. A slightly...
I will present results from a search for gamma-ray emission in
nine Milky Way satellites recently discovered in the Dark Energy
Survey. The nearest of these, Reticulum 2, shows evidence for a
signal in public Fermi data. The detected emission is...
Experimental constraints on models such as supersymmetry have
challenged our assumptions about naturalness, while simultaneously
pushing exploration into alternatives that might be more natural.
One such scenario is supersymmetry with Dirac...
In the presence of strong magnetic fields, the QCD vacuum may
become unstable towards condensation of charged rho mesons, forming
a superconducting state. I will talk about our investigation of
this possible instability in a well-known holographic...
Line operators in class S theories correspond to network operators
on the associated Riemann surface. I will describe the algebra of
functions on the moduli space of flat SL(N)-connections in terms of
a set of networks that are naturally associated...
I will describe recent work explaining how several paradoxical
features of bulk locality in AdS/CFT can be explained by
interpreting the CFT as a quantum error correcting code. Time
permitting I will also present an explicit discrete model of
this...
