In a Fermi liquid\, the shot noise signature reveals which scattering mechanism — electron-electron or electron-impurity — dominantly impedes charge motion and is thereby a window into the microscopic physics of an electronic system. However\, the understanding of shot noise in strongly correlated phases\, for which a quasiparticle picture may not be justified\, is far less advanced. In this talk\, I will share recent progress on this problem for a certain class of strongly-correlated systems. In particular\, I will present a theory of the non-equilibrium current response for metallic systems near quantum critical points where electronic quasiparticles fractionalize\, such as systems near continuous metal-insulator transitions. I will sketch the derivation of a non-perturbative current noise composition law\, wherein the total noise is the sum of the noise of each fractionalized constituent (bosonic holons and fermionic spinons)\, weighted by their respective resistivities. This composition rule can be interpreted in terms of a simple analogy with resistors in series. Lastly\, I will present an example of how quantum criticality can collude with fractionalization to suppress the measured shot noise in sufficiently long nanowires.

Universal MLIPs\, also called foundation models\, are trained across large\, chemically diverse datasets with the goal of broad transferability to new atomic environments. However\, the blackbox nature of MLIPs obscures the relationship between atomic environments and predicted outputs\, making it difficult to discern when the model is operating within its domain of validity and when its outputs may be unreliable. Uncertainty quantification (UQ) provides interpretable metrics that indicate the confidence or reliability of MLIP predictions. This talk will discuss UQ approaches using quantile regression to produce confidence intervals around the predicted output that can be used to assess the trustworthiness of MLIP-driven simulations. \nBio: Dr. Jenna Pope (who publishes under the name Jenna A. Bilbrey) is a Data Scientist at Pacific Northwest National Laboratory\, working within the National Security Directorate. Her research bridges computational chemistry\, materials science\, and AI/ML\, with a focus on applying deep learning and uncertainty quantification methods to chemical and materials modeling. She holds a PhD in computational chemistry from the University of Georgia and a BS in chemistry from the University of West Florida. Her projects are highly interdisciplinary and involve close collaboration with both experimentalists and theoreticians. Over the course of her career\, she has published on topics such as neural network potentials\, active learning for materials simulations\, and graph-component methods for defect analysis.  URL:https://www.quantumx.washington.edu/calendar/mse-seminar-jenna-pope/ LOCATION:maps.app.goo.gl… CATEGORIES:Materials Science & Engineering END:VEVENT END:VCALENDAR
