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.

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.

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.

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.

Join us at 1:00 p.m. (ET), Saturday, December 12, 2020, for PCCM's annual Holiday Lecture: 
A Materials Wonderland: A Celebration of How Materials Science Makes Our Holidays Fun

Russ Porter, Christopher Stubbs, and Benita Wolff will share their collective experience in moving Harvard further along the path to fully inclusive excellence.

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...
