Gravity Group Lunch Seminar, Saptarshi Chaudhuri | Princeton "Axions and DM Radio at Princeton"
Fri, Dec 18, 2020, 12:00 pm12:00 pm

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…

Special Seminar | Time-domain pulsed tunneling spectroscopy of two-dimensional electronic systems | Heun Mo Yoo | MIT
Thu, Dec 17, 2020, 1:00 pm1:00 pm

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…

Condensed Matter Zoom Seminar | Anton Kapustin, Caltech | "Higher-dimensional generalizations of the Berry curvature for gapped lattice systems"
Wed, Dec 16, 2020, 3:00 pm3:00 pm

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…

Special Seminar - Development of a single vacuum ultra-violet photon-sensing solution for the nEXO experiment and beyond | Giacomo Gallina | University of British Columbia
Wed, Dec 16, 2020, 2:45 pm2:45 pm

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…

FPO - Trithep Devakul - "Subdimensional Topological Quantum Phases of Matter"
Tue, Dec 15, 2020, 2:00 pm2:00 pm

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…

Special Seminar | Towards DarkSide-20k | Bianca Bottino | INFN
Tue, Dec 15, 2020, 2:00 pm2:00 pm

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…

Special Seminar | Optimizing the photon budget: 4D imaging of biological dynamics | Kevin Keomanee-Dizon | University of Southern California
Mon, Dec 14, 2020, 2:30 pm2:30 pm

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…

Special Seminar | Emergent phenomena in magnetic van der Waals heterostructures | Tiancheng Song | University of Washington
Mon, Dec 14, 2020, 1:30 pm1:30 pm

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…

Special seminar | Optimizing future CMB observatories and measuring galaxy cluster motions | Patricio Gallardo |Cornell University
Mon, Dec 14, 2020, 10:00 am10:00 am

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…

Special Seminar - Entanglement in an assembled array of single strontium atoms | Ivaylo S. Madjarov | Caltech
Wed, Dec 9, 2020, 2:30 pm2:30 pm

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…
