1. The Life and Death of Turbulence

   21 Feb 2019 | Online Presentations | Contributor(s): Nigel Goldenfeld

   In this presentation, I propose that turbulence is most fruitfully regarded as a problem in non-equilibrium statistical mechanics, and will show that this perspective explains turbulent drag behavior measured over 80 years, and makes predictions that have been experimentally tested in 2D...

2. Signatures of Nontrivial Topology in Weyl Semimetals and Fe-Based Superconductors

   13 Mar 2019 | Online Presentations | Contributor(s): Kenneth S. Burch

   In this talk I will outline our recent efforts to reveal non-trivial topology with nonlinear optics and tunneling spectroscopy. First I will focus on our efforts to use nonlinear optics to measure the Berry connection in the Weyl semimetal TaAs. Specifically using new FIB fabricated mesoscopic...

3. Manipulating Strongly Interacting Individual Quanta: Photon Molecules and 51 Atomic Qubits

   26 Mar 2019 | Online Presentations | Contributor(s): Vladan Vuletic

   I will discuss two applications: By coherently coupling light to Rydberg excitations in a dense atomic medium, we have realized a highly nonlinear optical medium where the interactions between individual photons are so strong that two photons can even form a bound state.

4. From Pseudogaps to Pair-Density Waves in Cuprate Superconductors

   15 May 2019 | Online Presentations | Contributor(s): John Tranquada

   I will present a fresh analysis of a large range of experimental characterizations, making the case for two pseudogaps: (1) a large pseudogap resulting from the competition between the energy of superexchange-coupled local Cu moments and the kinetic energy of doped holes; (2) a small pseudogap...

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

   22 May 2019 | Online Presentations | 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...

6. High-Precision Physics and Chemistry with Cold Molecules

   22 May 2019 | Online Presentations | Contributor(s): Tanya Zelevinsky

   We show how a combination of optical-clock style molecular spectroscopy and modern quantum chemistry shed light on quantum mechanical aspects of basic chemical reactions and advance table-top fundamental physics in new directions.

7. Soft Electronic and Microfluidic Systems for the Skin

   23 May 2019 | Online Presentations | Contributor(s): John A. Rogers

   This talk describes the key ideas, and presents some of the most recent device examples, including wireless, skin-like electronic 'tattoos' for continuous monitoring of vital signs in neonatal intensive care, microfluidic/electronic platforms that can capture, store and perform...

8. Suppression of Exciton Condensation in Copper-Doped TiSe2

   24 May 2019 | Online Presentations | Contributor(s): Melinda S. Rak

   This work establishes M-EELS as a versatile technique for studying a new class of macroscopic quantum condensates in condensed matter.

9. Search for Non-Newtonian Gravity with Optically-Levitated Microspheres

   31 Jan 2020 | Online Presentations | Contributor(s): Akio Kawasaki

   The universal law of gravity has undergone stringent tests for a long time over a significant range of length scale, from an atomic scale to a planetary scale. Of particular interest is the short distance regime, where modifications to Newtonian gravity may arise from axion-like particles and...

10. Toward a Thinking Microscope: Deep Learning-Enabled Computational Microscopy and Sensing

    29 Jan 2020 | Online Presentations | Contributor(s): Aydogan Ozcan

    In this presentation, I will provide an overview of some of our recent work on the use of deep neural networks in advancing computational microscopy and sensing systems, also covering their biomedical applications.

11. Putting Maxwell’s Demon to Work on Cooling Atoms and Efficient Isotope Separation

    26 Aug 2020 | Online Presentations | Contributor(s): Mark G. Raizen

    We are developing new approaches to the control of atomic motion, realizing the historic thought experiment of Maxwell’s demon exactly as envisioned by Maxwell in 1871.  This toolbox of new methods is an alternative to laser cooling and evaporative cooling of atoms, with much better...

12. The Eötvös Paradox: The Enduring Significance of Eötvös' Most Famous Experiment

    23 Aug 2020 | Online Presentations | Contributor(s): Ephraim Fischbach

    Here we summarize the key elements of this "Eötvös paradox," and suggest some possible paths to a resolution. Along the way we also discuss the close relationship between Eötvös and Einstein, and consider how their respective contributions may have been influenced...

13. Portrait of a Black Hole & Beyond

    26 Aug 2020 | Online Presentations | Contributor(s): Katie L. Bouman

    Dr. Bouman, who was part of the Event Horizon Telescope team that captured the first photograph of a black hole, will talk about the challenges of the project.

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

    28 Aug 2020 | Online Presentations | 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.
