1. High Impedance Hall Measurements and the Fully Guarded Insert

   16 Apr 2024 | | Contributor(s):: Jeffrey Lindemuth

2. Quantum Hall Characterization and a Balanced Current Source

   16 Apr 2024 | | Contributor(s):: Emilio Codecido

3. Fractionalization of Charge and Statistics in Two Dimensions

   14 Dec 2022 | | Contributor(s):: Michael J. Manfra

   This lecture will focus on the development of experiments that allow the first direct observation of anyonic braiding statistics in the fractional quantum Hall regime. The connection between development of new theoretical concepts and the behavior of a humble transistor will be emphasized.

4. Fundamental Properties of a New van der Waals Material: Tellurium

   01 Apr 2021 | | Contributor(s):: Peide "Peter" Ye

   We report the first experimental observation of Weyl fermions in a semiconductor -- high-quality n-type tellurene (the two-dimensional form of tellurium) achieved by atomic layer deposited dielectric doping.

5. Engineering Rashba Spin-Orbit Coupling for a Bose-Einstien Condensate

   28 Aug 2020 | | Contributor(s):: Ian B. Spielman

   I will describe our engineered Rashba spin-orbit coupling for a cold atomic gas giving non-trivial topology, without the underlying crystalline structure that conventionally yields integer Chern numbers.

6. Resistively-Detected NMR and Nuclear Resonance Imaging

   07 May 2020 | | Contributor(s):: Yoshiro Hirayama

   NMR provides us versatile tool to physical, chemical, biological, and medical characterizations. However, conventional NMR suffers low sensitivity and cannot be applied to semiconductor quantum systems, such as single quantum well or wire. To overcome these difficulties,...

7. Mini Course on Physical Models

   04 Sep 2019 | | Contributor(s):: Bruno Uchoa

   This mini-course of four lectures is intended to stimulate undergraduate students to think critically about the the modeling process in physics.

8. Aharonov-Bohm Interference of Fractional Quantum Hall Edge Modes

   20 Jun 2019 | | Contributor(s):: Michael J. Manfra

   The braiding statistics of certain fractional quantum Hall states can be probed via interferometry of their edge states. Practical difficulties – including loss of phase coherence – make this a challenging task. We demonstrate the operation of a small Fabry-Perot interferometer in...

9. Nanoscale NMR Studies of Topological Insulators, Crystalline Insulators and Dirac Semimetals

   22 May 2019 | | Contributor(s):: Louis Bouchard

   In this talk, we will review recent advances in experimental techniques to study the electronic and magnetic properties of such topological materials.  Among the novel techniques, we shall discuss radioactive ion beam spectroscopy and nuclear magnetic resonance.   Our group has...
