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.

This webinar will provide an overview of El Niño and La Niña and their global impacts. We will review the strong El Niño of 2023–24 and the current forecast for the rest of 2024. We will also cover what is understood about ENSO and global warming. Originally aired April 2024.

Stochastic models are ubiquitous in nature. They are applicable to the diffusion of molecules (which, when combined with Albert Einstein’s theory, provided the first proof for the atomistic nature of matter), the way through which random mutations drive evolutionary dynamics, and more…Watch the video to learn more!

Using only lasers, this research group has accelerated electrons to 5 GeV. The acceleration, which takes place over only 20 cm, is approximately 20% of the acceleration achievable at the Stanford Linear Accelerator over 3 km…Watch the video to learn more! Originally aired October 2023.

A recently uncovered cache of materials that neutrino pioneers Clyde Cowan and Fred Reines collected includes records, keepsakes, and images that were packed away shortly after the electron antineutrino was first discovered in the flux from a reactor in South Carolina in 1956. Notes, images, and invoices offer an intimate glimpse of the efforts that led to first direct detection of neutrinos. Originally aired July 2023.
