Magnetism has been in the forefront in our understandings of protoplanetary disks (PPD) and planet formation. With the prevalence of disk substructures, a major observational revolution over the past few years, PPDs are now considered as “planet...

Abstract 1: Measurements of the Hubble constant (H0) as determined via the Cepheid-supernovae distance ladder appear to provide strong evidence for physics beyond LCDM. However, in the Carnegie Chicago Hubble Program (CCHP), we used the Tip of the...

The area operator plays a central role in our understanding of holography and black hole thermodynamics. In this talk I will discuss a formulation of the area operator at the level of classical gravity, the “kink transform”, which defines a notion...

The giant impact theory for the formation of the Moon suggests that a planetary impactor struck the proto-Earth in an oblique collision shortly after the formation of the solar system. This collision produces liquid and vapor debris, drawn from the...

The past decade has seen the emergence of surprising new connections between the real-world physics of elementary particle scattering processes, and simple new mathematical structures in combinatorics, algebra and geometry. These ideas provide, in a...

Cosmic rays, the relativistic component of diffuse astrophysical plasma, exchange energy and momentum with the thermal gas collisionlessly, mediated by the ambient magnetic field. Some but not all models of this interaction show that cosmic rays can...

The prospect of an ultra-light dark matter particle (also known as Fuzzy Dark Matter, or FDM) has recently drawn attention as a promising alternative to standard Cold Dark Matter (CDM). When the mass of the particle reaches below 10^-21 eV, quantum...

Edge excitations of (2+1)D topological phases are usually described using continuum field theories. But the boundaries of some (2+1)D topological phases can also be described using lattice-like edge theories that have a finite dimensional Hilbert...
