Improving neural network based equations solvers - LivestreamNeural Networks (NNs) have ushered in new methods of constructing solution approximations to complex mathematical equations. However, especially in the context of Differential Equations (DEs), such approximations are often reliant on external methods/solutions to reliably estimate the errors associated with them. This occurs because cost functions are seldom explicitly dependent ...

Dipolar excitonic insulator in atomic double layers - LivestreamThe excitonic insulator (EI) is a charge insulating state that arises from the spontaneous formation of bound electron-hole pairs (excitons). It presents an interesting platform for realizing quantum many-body ground states of bosons in solids, such as condensate and superfluid. Although the concept has been known for sixty years, to ...
I present a new measurement of the positive muon anomalous magnetic moment a_μ=(g_μ-2)/2 from the Fermilab E989 experiment.  The quantity a_μ is an exquisite probe of the quantum corrections of the muon interaction with the electromagnetic field. The experiment is a follow up of the BNL E821 experiment, which saw ...
Affordable, reliable, ever-cleaner energy is essential to achieve a more prosperous and sustainable world. Reducing the carbon intensity of the energy that billions of people rely on every day is a tremendous opportunity to advance the global net zero ambitions of the Paris Agreement. At Chevron, we use our unique ...
Measuring your ingredients: topological phases for quantum computing - LivestreamTopological quantum computing relies on qubits encoded in quantum states that are exponentially protected from local perturbations. One method for realizing such protected states is a practical recipe for topological superconductivity: hybrid superconductor-semiconductor nanowires in finite magnetic fields. In this talk I will describe experimental methods for identifying and manipulating ...

Virology 101What ARE viruses? Join us for a virtual talk by Columbia University professor Dr. Vincent Racaniello, who will explain what viruses are and how they work, followed by a wide-ranging discussion on the COVID-19 pandemic. He will cover the origins of the virus, the disease, how it is diagnosed, and ...
