|
| Coherent control of wave propagation in opaque materials |
Concept of diffusion is widely used to describe propagation of light through multiple scattering media such as clouds, interstellar gas, colloids, paints, biological tissue, etc. Such media are often called random. This terminology is, however, misleading.… Show more Speaker: Prof. Alexey Yamilov, Department of Physics, Missouri S & T |

Abtract: In this talk, I will discuss how antiferromagnetic (AFM) domains and their boundaries—known as domain walls—form and evolve in MnBi2Te4, the first experimentally discovered antiferromagnetic topological insulator. To probe these magnetic textures, we… Show more Speaker: Prof. Min Gyu Kim, University of Wisconsin-Milwaukee |
|
| Light alkane conversion through catalytic structures and pathways design |
Light alkane, such as ethane and propane, are ubiquitous in natural gas and the by-products of the various waste-, biomass-, and power-to-X processes. However, the transformations of light alkane, due to the inert C-H bonds, remain a formidable challenge.… Show more Speaker: Prof. Yizhi Xiang, University of Missouri |
|
| Is the Stellar Initial Mass Function Universal? | Speaker: Prof. Charles Steinhardt |
|
| Entangled Pauli Principles |
Abstract: One of the enduring questions in the study of strongly correlated electrons is how to read the universal, long-distance physics directly from a microscopic Hamiltonian. In fractional quantum Hall systems, certain solvable models achieve this through… Show more Speaker: Prof. Alexander Seidel, Department of Physics, Washington University in St. Louis |

Abstract: Spintronics is a field of research and technology that exploits the electron’s spin—a quantum property responsible for magnetism—along with its charge, as used in conventional electronics. In spintronic devices, information can be stored, processed, and… Show more Speaker: Prof. Evgeny Tsymbal, University of Nebraska-Lincoln |
|
| Electron Transport and Topological Hall Effect in Skyrmion Crystals |
Magnetic skyrmions are topologically protected spin configurations that have gained enormous interest as building blocks for next-generation spintronic devices. A distinctive feature of skyrmion systems is the topological Hall effect (THE): when electrons… Show more Speaker: Prof. Sashi Satpathy, University of Missouri |
|
| Exams with More Learning and Less Stress with a Computer-based Testing Facility |
Abstract: Exams are an important tool for summative assessment, whose utility has only grown with the advent of large language models (LLMs) like ChatGPT, because they can be implemented in a trustworthy manner. But exams are generally not well liked by either… Show more Speaker: Prof. Craig Zilles, University of Illinois at Urbana-Champaign |
|
| Multiferroic phase transitions in polar magnets |
Multiferroics refers to compounds where more than one ferroic order such as (anti)ferromagnetism, ferroelectricity, ferroelasticity etc. coexist.
