Abstract: Quantum information science seeks to
exploit the collective behavior of a large quantum system to enable
tasks that are impossible (or less possible!) with classical
resources alone. This burgeoning field encompasses a variety
of...
Discs of stars around super-massive black holes, like the one at
the Galactic centre, evolve primarily via resonant relaxation,
which is the process governing the evolution of the
angular-momentum vectors of stellar orbits about the
super-massive...
Abstract: The PADME experiment is a
fixed-target high-energy physics setup located in Frascati, Italy,
originally designed to search for dark photon production via
collisions between a positron beam and a thin diamond target. In
2022, the experiment...
Surveys of the mm-wave sky are great resources for astrophysics
and cosmology. Sources that have been studied include solar system
objects, flaring stars, accreting black holes, dusty star forming
galaxies, and galaxy clusters, while cosmological...
Abstract: I discuss a holographic duality
between the SYK model in a double scaling limit and a 2d theory of
quantum cosmology called sine dilaton gravity.
The evolution of planets and planetary systems depends on the
environments created by their host stars in a number of ways.
In this talk, I will discuss several observable impacts of stellar
winds, radiation pressure, and non-thermal ionizing...
Abstract: We discuss relaxation solutions to
the dark matter - baryon coincidence problem in the context of QCD
axion dark matter. In relaxation solutions, a moduli dynamically
adjusts the mass of dark matter and baryons until their energy
densities...
Massive black holes (MBHs) exist at the centers of many dense
star systems, particularly in galactic nuclei. Steady
accretion onto MBHs powers active galactic nuclei, but dynamical
processes near MBHs can generate various forms of transient...
I will present a program of extracting cosmological information
by combining effective field theory (EFT) techniques with data from
spectroscopic galaxy surveys. I will highlight previous successes
of this program and share recent results, including...
