Equation of state constraints from kilonova spectra and signatures of hyperons

The importance of GW170817 for equation of state constraints was immediately obvious after the event with various ideas that were proposed to learn about the properties of high-density matter. Recently, […]

The r-Process: A Complete Survey and the Impact of Ab Initio Masses

Please contact divya.singh@berkeley.edu, tianqi.zhao@berkeley.edu, or klund@berkeley.edu for zoom links. The rapid neutron-capture (r-) process is responsible for producing approximately half of the elements heavier than iron in the Universe. However, […]

Parity and Baryogenesis in Theories Beyond Standard Cosmology

Please contact divya.singh@berkeley.edu, tianqi.zhao@berkeley.edu, or klund@berkeley.edu for zoom links. Motivated by open questions such as the matter-antimatter asymmetry, the dark sector, and a quantum theory of gravity, I will talk […]

The Effective Theory of Muon-to-Electron Conversion

We summarize recent work to develop an effective theory of muon-to-electron conversion, based on a complete set of low-energy effective operators that are developed from a systematic expansion in velocities […]

Whispers of the Stars: The Tale of ²³Na and Elusive Axions

In the crushing heat and density of stellar interiors, ordinary matter behaves in extraordinary ways, and, if some bold ideas in theoretical physics are correct, stars may also be producing entirely new kinds of particles: axions and axion-like particles, or ALPs.
