In this webinar, we describe a new approach to directly see the physics inside a DAC at ultrahigh pressures. The basic idea is deceptively simple: We directly integrate a thin layer of nitrogen–vacancy defects, which serve as quantum sensors, into the diamond surface. We demonstrate the ability to perform optical diffraction-limited imaging of both stress fields and magnetism, with the latter allowing us to image the magnetic field expulsion associated with superconductivity. …

We will present a breakthrough approach that overcomes those limitations using metasurfaces—ultrathin, nanostructured optical elements that precisely shape light at the subwavelength scale. We demonstrate the first experimental realization of a compact, single-shot, and complete Mueller matrix imaging system, enabled by two carefully engineered metasurfaces: one to generate structured polarization illumination and another to perform full polarization analysis.

Following recent advances in photonics design, fabrication, and heterogenous integration, we demonstrate that a tunable continuous wave Titanium:sapphire (Ti:sapphire) laser can be miniaturized into sub-cubic centimeter volume together with its pump.…

Lithium-ion batteries contain porous electrodes separated by an ion-permeable membrane. Those electrodes are manufactured by coating metal foils with battery slurry, a complex fluid that contains the raw materials that make the batteries function. We will present the foundations of a physics-based understanding of battery slurry behavior under flow, with a special emphasis on evolving material microstructure. We will take a close look at the unique tools that can explore this microstructure at the relevant length scale and in the relevant environment. We will show that these findings have relevance to the prediction of both the battery slurry rheology and the coated properties of battery electrodes, thereby improving the efficiency of battery manufacturing.

In this webinar, we will present a scheme for a neuromorphic system that relies on linear wave scattering and yet achieves nonlinear processing with high expressivity. The key idea is to encode the input in physical parameters that affect the scattering processes. Moreover, we show that gradients needed for training can be directly measured in scattering experiments. We propose an implementation that uses integrated photonics based on racetrack resonators and achieves high connectivity with a minimal number of waveguide crossings.

Across science, many groups of people continue to be underrepresented, and representation gaps appear set to persist for a long time. For example, it is projected to take 258 years to reach gender parity in physics. What factors lead to disparities in representation? What are the challenges faced by equity-deserving groups? Why should we be motivated to effect change? What can we do? Originally aired February 2023.
