In the late 1970s, the axion was proposed as a solution to the strong CP problem, ie, the
puzzle why the strong interactions conserve parity P and the product CP of charge …

This article reviews recent developments in tests of fundamental physics using atoms and
molecules, including the subjects of parity violation, searches for permanent electric dipole …

We study the direct detection prospects for a representative set of simplified models of sub-
GeV dark matter (DM), accounting for existing terrestrial, astrophysical and cosmological …

Uncovering the nature of dark matter is one of the most important goals of particle physics.
Light bosonic particles, such as the dark photon, are well-motivated candidates: they are …

The last decade has seen unprecedented effort in dark matter model building at all mass
scales coupled with the design of numerous new detection strategies. Transformative …

We propose the use of superconducting nanowires as both target and sensor for direct
detection of sub-GeV dark matter. With excellent sensitivity to small energy deposits on …

Quantum sensing and metrology use coherent superposition states of quantum systems to
detect and measure physical effects of interest. Their sensitivity is typically limited by the …

These lectures provide an introduction to models and direct detection of dark matter. We
summarize the general features and motivations for candidates in the full dark matter mass …

We propose the use of silicon carbide (SiC) for direct detection of sub-GeV dark matter. SiC
has properties similar to both silicon and diamond but has two key advantages:(i) it is a polar …

The next generation of axion direct-detection experiments may rule out or confirm axions as
the dominant source of dark matter. We develop a general likelihood-based framework for …
