A joint colloquium from the Physics Department and the Functional Analysis and Mathematical Physics (FAMP) Interdepartmental Research Group

Title:  Fermionic Superfluidity: from Cold Atoms to Neutron Stars

By Dr. Ettore Vitali, California State University, Fresno, Department of Physics

See the announcement as a PDF.

Abstract: In this presentation, I will provide an overview of fermionic superfluidity, which is a very interesting and puzzling phenomenon that occurs in some of the most mysterious systems in the universe, like unconventional superconductors and neutron stars. I will discuss the basic physical mechanism, involving a subtle interplay among quantum mechanics, quantum statistics and interatomic forces. I will also stress the importance of cold atoms as one of the most promising "laboratories" to observe Fermi superfluidity in a controlled environment. Finally, I will discuss many open exciting research opportunities in theoretical and computational physics related to superfluid fermions.

Title: The Rise of Artificial Intelligence and an Application in Observational Astronomy

By Dr. Athanasios Aris Panagopoulos, California State University, Fresno, Department of Computer Science.

See the announcement as a PDF.

Abstract: In recent years, artificial intelligence is increasingly becoming an integral part of our everyday life, assisting in solving challenging problems in various domains such as energy sustainability, transportation, medicine, and physics. This shift is supported by concurrent advances in computational and data storage technologies, connectivity, data availability, and theoretical understanding. In this context, AI is also altering the way we do research and get to know the world around us. In this talk, we will delve into the essence of the AI revolution and investigate its potential in supporting our research endeavors. We will see how AI builds on the basic principles of natural/biological intelligence, the challenges, and current trends. Importantly, we will investigate how AI can assist our research by automatically detecting patterns in our data. As a particular example, we will explore how AI can help to detect r-mode gravitational wave signals from newborn neutron stars using artificial neural networks and pattern recognition techniques.

Title "A Shift Toward Scientific Reasoning: The Introductory Physics Lab" by Dr. John Walkup, Roger Key, and Stephan Squire

Abstract: "For the past year, John Walkup and Roger Key have spearheaded a transformation of our introductory physics labs to elevate scientific reasoning. In a revised lab manual that is currently under development, every one of our existing PHYS-4A lab activities would either receive an overhaul or be replaced altogether. These efforts have culminated in four publications, with another one in preparation. Stephan Squire, a graduate student of physics at the time, measured the efficacy of this new approach in his M.S. thesis research, although the sample sizes were likely too small to generate conclusive results. In this colloquium, John, Roger, and Stephan will discuss this new paradigm in lab design and how it alters the learning environment for our future scientists and engineers."
