  Speaker: Professor Tim Mewes (University of Alabama)

  Date: Monday March 16, 2020. Tech L440 2-3pm

  Abstract: The dynamics and the damping of magnetization are of paramount importance to understand and predict the properties of magnetic materials used in a variety of applications. For example, spin-transfer torque magnetic random-access memory cells (STT-MRAM) are expected to switch fast, reliably, and with low power consumption, which requires low damping materials. New spintronic devices based on magnetic skyrmions, which also demand precise control of the magnetization dynamics, are another example. The Landau-Lifshitz-Gilbert equation of motion [1, 2] and extensions thereof [3] have been extremely successful in enabling predictions of the magnetization dynamics of materials both analytically and using micromagnetic simulations. Experimentally the magnetization dynamics can be elegantly probed in the frequency domain using ferromagnetic resonance (FMR). Recent progress in broadband ferromagnetic resonance techniques have provided valuable new insights in the magnetization dynamics and the damping mechanisms of magnetic materials.

  In this lecture, I will introduce the fundamentals of magnetization dynamics and damping. I will discuss their importance for many applications, including hard drive read heads, spin-transfer torque magnetic random-access memories and new skyrmions based devices. I will talk about various mechanisms that can contribute to the damping of the magnetization in thin films including spin-orbit relaxation, spin pumping, and two-magnon scattering. The presentation will show how recent developments in broadband ferromagnetic resonance enable precise measurements of the dynamics and damping in thin magnetic films and multilayers especially when combined with angle and temperature dependent measurements. This will include a discussion of the recently discovered anisotropic damping in exchange biased films

  Biography: Tim Mewes received his undergraduate degree in physics in 1999 from the University of Kaiserslautern in Germany. He received his Ph.D. in physics from the same University in 2002. He subsequently was a postdoctoral researcher at Ohio State University. He joined the University of Alabama in 2005, where he now works as a professor in the Department of Physics and Astronomy.

  Prof. Tim Mewes has published over 70 articles in peer reviewed journals on topics including epitaxial growth of magnetic thin films, exchange bias, influence of ion irradiation on magnetic properties, magnetic resonance force microscopy, broadband ferromagnetic resonance, magnetization dynamics, damping, and micromagnetics.

  During his undergraduate and graduate studies Tim Mewes was a scholar of the German Academic Scholarship Foundation. In 2010 Prof. Mewes received a National Science Foundation CAREER award for the investigation of the magnetization dynamics and damping in magnetic nanostructures. In 2011 he became a Visiting Fellow of the Center for Nanoscale Science and Technology at the National Institute for Standards and Technology in Gaithersburg, and in 2014 he received the IBM Faculty Award. Dr. Mewes currently chairs the Alabama chapter of the IEEE Magnetics Society. He chaired the 2016 IEEE International Conference of Microwave Magnetics in Tuscaloosa and has been active on program committees of several other international magnetism conferences. He is also a member of the American Physical Society.

  CS Distinguished Lecture: Trustworthy Conversational Chatbots for Your Data with Generative AI (Monica Lam)

  Department of Computer Science (CS)

  EVENT DETAILS

  Speaker

  Talk Title
  Trustworthy Conversational Chatbots for Your Data with Generative AI

  Abstract
  The rapid growth of Large Language Models (LLMs), such as ChatGPT, has both inspired and alarmed knowledge workers. LLM-based chatbots generating false information and hallucinating have garnered widespread attention, raising questions about the reliability of LLMs as chatbots and virtual assistants.

  The Stanford Open Virtual Assistant Lab has created an open-source Knowledge Engine, powered by an LLM, that can provide a reliable conversational chatbot to any structured or unstructured data. It can also assist writers by drafting full-length Wikipedia-like articles from scratch with breadth and depth. Public demos created with our Knowledge Engine include: WikiChat grounded in Wikipedia, Yelpbot grounded in Yelp, the STORM writing assistant grounded in the Internet, and Noora, a coach for people with Autism Spectrum Disorder (https://oval.cs.stanford.edu).

  Biography
  Dr. Monica Lam is the Kleiner Perkins, Mayfield, Sequoia Capital Professor in the School of Engineering at Stanford, in the Departments of Computer Science and, by courtesy, Electrical Engineering. She is the Faculty Director of the Stanford Open Virtual Assistant Laboratory and a faculty member of the Natural Language Processing Group at Stanford. She received a B.Sc. from University of British Columbia and a Ph.D. from Carnegie Mellon University.

  Prof. Lam is a member of the National Academy of Engineering and an ACM Fellow. She has received numerous best paper awards, and has published over 150 papers in areas including natural language processing, machine learning, compilers, computer architecture, operating systems, high-performance computing, and HCI. She co-authored the “Dragon Book”, the definitive text on compiler technology. She was on the founding team of Tensilica, the first startup in configurable processor cores. Prof. Lam's research on privacy-preserving virtual assistants earned Popular Science's Best of What's New Award in Security in 2019.

  ECE Distinguished Seminar - Yue Lu

  Department of Electrical and Computer Engineering (ECE)

  2:00 PM L440, Technological Institute

  EVENT DETAILS

  Universality is a fascinating high-dimensional phenomenon. It points to the existence of universal laws that govern the macroscopic behavior of wide classes of large and complex systems, despite their differences in microscopic details. The notion of universality originated in statistical mechanics, especially in the study of phase transitions. Similar phenomena have been observed in probability theory, dynamical systems, random matrix theory, signal processing, and machine learning. In this talk, I will present some recent progress in rigorously understanding and exploiting the universality phenomenon in the context of statistical estimation and learning on high-dimensional data. Examples include spectral methods for high-dimensional projection pursuit, statistical learning based on kernel and random feature models, approximate message passing algorithms, structured random dimension reduction maps for efficient sketching, and regularized linear regression on highly structured, strongly correlated, and even (nearly) deterministic design matrices. Together, they demonstrate the robustness and wide applicability of the universality phenomenon.

  Trust, Backdoor Vulnerabilities and Possible Mitigations

  Abstract
  Cryptographic tools and models enable to trust the use of technology platforms controlled by worst case computationally bounded adversaries.
