I introduce DM Radio, a lumped-LC oscillator search for axion dark matter. I review the detection scheme and design, current experimental status, and future prospects, including the use of electromagnetic quantum metrology in previously-unexplored kHz and MHz frequency ranges. Experimental efforts at Princeton, in particular probes of loss…
Two-dimensional (2D) electronic systems host a plethora of remarkable phenomena, including the integer and fractional quantum Hall effects (Nobel Prize 1985 and 1998), and have stimulated a wide range of fundamental science and engineering research. Yet, many of the important phenomena that emerge from the collective behavior of 2D electrons…
Building on the work of von Neumann and Wigner, M. Berry showed that there are topologically protected level-crossings in the space of quantum systems. These level-crossings can be detected using the curvature of the Berry connection. In this talk I will describe analogs of this for interacting lattice systems in infinite volume. Although the…
Silicon PhotoMultiplier (SiPM) technology represents an unprecedented attempt to create an ideal solid-state photon detector combining the low-light detection capabilities of the previous device generations with all the benefits of a solid-state sensor. For this reason, large-scale low-background cryogenic experiments, such as Darkside-20k…
This Dissertation concerns phases of matter with various ``subdimensional'' properties. We start with topologically ordered phases with subdimensional properties. This includes a discussion of fracton topologically ordered phases, resonating valence plaquette phases, and floating topological phases. We then move on to discuss systems with…
The DarkSide-20k experiment will perform a comprehensive search for high-mass WIMPs using a dual phase argon time projection chamber (TPC) located in the Gran Sasso National Laboratories (LNGS), in Italy. DarkSide-20k is planned to run for ten years, accumulating a total exposure of 200 t yr, and will have sensitivity to a WIMP-nucleon cross…
In the last few decades, there have been transformative advances in optical microscopy that now offers us the ability to observe the organization and dynamics of biological systems at high resolution in space and time. Such 4D imaging, however, is challenged by unavoidable tradeoffs between spatial resolution, acquisition speed, penetration…

Van der Waals (vdW) heterostructures built by the vertical stacking of various 2D materials provide an ideal platform for the rational design of emergent phenomena. The recent discovery of atomically thin magnetic vdW materials has created new opportunities to explore 2D magnetism in magnetic vdW heterostructures. In…
Ground-based high-throughput millimeter-wave cosmic microwave background (CMB) experiments have provided invaluable clues of the history and composition of the universe. Future surveys will expand our understanding of inflation, the composition and distribution of dark matter in the universe, and will provide an…

Russ Porter, Christopher Stubbs, and Benita Wolff will share their collective experience in moving Harvard further along the path to fully inclusive excellence.
Abstract: We will share our collective experience in moving Harvard further along the path to fully inclusive excellence. This is a high priority for the…

The recently-developed technique of atom-by-atom assembly has allowed for the generation of large atomic qubit registers with zero defect entropy. When the atoms in such a system are excited to Rydberg states, they experience long-range interactions that enable many-body interatomic entanglement of their internal…
Quantum gas microscopes provide experimental access to novel observables, foremost, single particle resolved multi-point correlation functions. These offer a novel microscopic window into the physics of strongly correlated many-body physics. In our setup we developed a method for the simultaneous detection of spin and…
The Cosmology Large Angular Scale Surveyor (CLASS) is an array of polarization-sensitive millimeter wave telescopes that observes ∼70% of the sky at frequency bands centered near 40GHz, 90GHz, 150GHz, and 220GHz from the Atacama desert of northern Chile. The primary science goals of CLASS are two-fold: to search for polarization B-modes in the…
