Abstract 1: The axion, motivated as a solution to the strong CP problem, is also a viable dark matter candidate. If the initial axion field is not homogenized by inflation, it can naturally imprint large isocurvature fluctuations at extremely small...

I will introduce the topic of heavy multiquark states, with special attention to the current theoretical and experimental status. I will first review the available experimental information and then discuss them in the context of the two most likely...

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...
