Education workshop series partnership with AAPT: Integrating Customizable e-Texts and Digital Lab Notebooks into your Classroom
To better meet student needs, many physics instructors desire to customize Open-Source Educational Resource (OER) textbooks in order to insert links to current events, embed videos or simulations, alter the wording or images, etc. Currently there is no seamless way for instructors to do this. In this workshop, participants will be introduced to an intuitive editor that will enable an instructor to make any desired customizations/changes to an OpenStax textbook.
In this webinar, we demonstrate a software platform that allows researchers to speed up QPU tune-up, have an in-depth understanding of qubit parameters, improve their qubits, and be able to work more efficiently with their chips. Specifically, we will break down the qubit characterization workflow into physical control segments and explain the physics behind those segments.

Fundamental elementary particle physics allows pointlike electric charges, such as electrons, and pointlike magnetic charges, sometimes referred to as magnetic monopoles, to exist in our universe. Despite decades of searching, the latter have never been observed in particle experiments. All is not lost, however, because emergent magnetic monopoles are thought to occur in lanthanide pyrochlore magnetic insulators.
Deep learning is an exciting approach to modern artificial intelligence that is based on artificial neural networks. The goal of this talk is to provide a blueprint—using tools from physics—for theoretically analyzing realistic deep neural networks.
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?
Editor’s Series: Science on a Mission: How Military Funding Shaped What We Do and Don't Know About the Ocean

We will also review some of the historical ideas on the subject.
Photons are excellent carriers of quantum information over long distances and can be reliably processed in advanced photonic integrated circuits. One fundamental challenge has been that they are complex to generate, i.e. single-photon sources tend to be inherently inefficient. Solid-state quantum emitters deterministically coupled to nanophotonic circuits have overcome this challenge, and today highly efficient and coherent photon-emitter interfaces are realized, enabling generation of high-quality single-photon sources, multi-photon entanglement sources or photonic quantum gates. In this webinar we will explain the fundamental operational principle of this novel light-matter interfaces and discuss future application areas within quantum computing and quantum networks.
Characterization and properties of color centers in Silicon for integrated quantum information processing at near IR and telecom wavelength and technologies for their spectral characterization
Optically active color centers in the solid state are leading candidates for quantum information processing due to long spin coherence times, and high-quality spin-photon interfaces, but traditional platforms based on diamond and silicon-carbide suffer from manufacturability and optical interfacing limitations. Color centers in Silicon are emerging qubit candidates operating at telecom wavelength. Platforms based on silicon color centers can leverage the mature toolbox of large-scale silicon photonics and thousands of miles of deployed optical fiber. The webinar will discuss fabrication and properties of silicon color centers, integration into photonic devices as well as technologies necessary to detect the low light level spectral emission required for their spectral characterization.
Editor’s Series: Zapping gases with lasers to amplify and detect tiny concentrations of electric charge
After the demonstration of the laser in 1960, researchers quickly discovered that tightly focused laser pulses generated a bright spark of ionized air. The physics of this process-- a laser-driven exponential growth of charge-- was well-understood by the end of the 1960s. An obvious potential application was extreme sensitivity charge detection in gases through the amplification of individual free electrons, in analogy to the detection of single photons or electrons by multiplier tubes. However, various technical and physics limitations delayed this application until very recently.
In this presentation I will describe the avalanche process and discuss how we overcame these limitations to develop an ultrasensitive charge detection diagnostic.
Most colored materials owe their color to the absorption of light. In nature we often see a different type of coloration, known as structural color: certain wavelengths are transmitted, while others scatter and constructively interfere. Structural colors are common in birds and particularly in blue feathers, which consist of disordered arrays of pores that scatter light.
Whirlwinds caused by thermal updrafts can pick up dust and become visible, forming 'dust devils'. Largely a harmless curiosity in desert meteorology, they can cause occasional damage. Like earthquakes, there are many small ones, and a few intense ones; the distribution of diameters, or core pressure drops, seems to follow a power law…
The sparking of grapes in a household microwave oven has been a popular online parlour trick for decades. Traditional explanations presume that the objects act as conductive short antennas.

This webinar explores jugglers' dependence on muscle memory and dynamical prediction. If every throw is considered to be an independent event, there exist juggling patterns in which the reaction time required to make successive catches and the precision needed to make perfect throws exceeds human capabilities. Using simulations with Gaussian deviations applied to throw angles and velocities, we reinforce this claim and compare the stability of various juggling patterns known as siteswaps. We show that throw angles and velocities affect very distinct aspects of juggling performance, and we obtain criteria on each that are needed to avoid juggling failures.
