In this talk we'll explain how self-dual metrics (which correspond
to spacetimes containing only positive helicity gravitons) can be
written as a sum over connected "tree" diagrams, which are
different...
Planetary systems are shaped as much by destructive
processes --- N-body instabilities, catastrophic impacts, and
atmospheric loss --- as by accretionary ones. We examine the
histories of violence written in: (a) the orbital architectures of
super...
A key challenge for computation is solving problems in high
dimensions. Two classic proposals for tackling high dimensional
problems are the Bethe approximation, or "belief propagation", and
the quantum Fourier transform. Tensor networks offer a...
In this talk I will review the current state of and future
prospects for exoplanet demographics. I will walk through the
latest understanding of the frequency of Earth-like planets from
Kepler, and their implications for NASA’s next flagship
mission...
The recent breakthrough in the detection of gravitational waves
(GWs) from merging black hole (BH) and neutron star (NS) binaries
by advanced LIGO/Virgo has generated renewed interest in
understanding the formation mechanisms of merging compact...
I will introduce a new 2d gravity/matrix integral duality. The
bulk theory is a two-dimensional string theory defined by coupling
two copies of Liouville CFT with central charges c = 13 ± is on the
worldsheet. We call this string theory the complex...
Supermassive black holes at the centers of galaxies present
unsolved theoretical challenges for our understanding of
high-energy astrophysics, gravity and gravitational waves, star and
galaxy formation, and space plasma physics. For decades, our...
