| Strong Lensing by Galaxies: Review of the Past, Present & Future | Speaker: Alec Martin |
|
| Electron Correlation Effects in Solid-state High Harmonic Generation with First-Principles Calculations |
High harmonic generation (HHG) is an extreme non-linear phenomenon where strong laser-field pulses interact with a medium to produce coherent and high-frequency harmonics of the incident light. Since its first observation in solids in 2011, pioneering… Show more Speaker: Dr. Didarul Alam, University of Missouri |

| 2023 Nobel Prize in Physics Attosecond light pulses: taking snapshots of electrons in matter |
The Nobel Prize in Physics 2023 was awarded to three physicists, Pierre Agostini, Ferenc Krausz, and Anne L’Huillier, for “experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter”. Prof. Carsten Ullrich, MU Dept. of… Show more Speaker: Dr. Carsten Ullrich |
|
| Inversion and time-reversal symmetry broken Weyl semimetal |
Weyl semimetals are among the materials proposed to have significant potential in informational technologies and to harbor the necessary elements for quantum computing. They host Weyl nodes at specific points in their Brillouin zone, a pair of relativistic… Show more Speaker: Prof. Halyna Hodovanets, Missouri S&T |

|
| Characterizing the true descendants of the first stars | Speaker: Harold Quiroz |
|
| O.M. Stewart Colloquium |
Abstract: Epithelial tissues are the first and most abundant tissue type in animals. They can be found in basal organisms like sponges, and they perform a wide range of important biological functions (including gas exchange and nutrient absorption) in humans. These… Show more Speaker: Dr. Dan Bergstralh |
|
| Insights into Black Hole Growth in the Early Universe with JWST | Speaker: Prof. Dale Kocevski (Colby College) |
|
| Emergent magnetism with continuous control in layered quantum materials |
Matthew Brahlek, Materials Science and Technology Division, Oak Ridge National Laboratory
The current challenge to realizing continuously tunable magnetism lies in our inability to systematically change properties such as valence, spin, and orbital degrees of… Show more Speaker: Dr Matthew Brahlek |

Speaker: Undergraduate Students |
|
| Philosophical reflections on quantum gravity phenomenology |
Abstract:
Long-standing common lore in fundamental physics insists that the problem of developing a high-energy theory of quantum gravity (QG) is a job for the theoretical physicist, which is largely unconstrained by empirical data. But QG phenomenology --- focused… Show more Speaker: Dr. Mike Schneider, Department of Philosophy at the University of Missouri |

| "Resolving" tension between JWST observations and LCDM | Speaker: Alec Martin |
|
| Energetic Constraints on Biological Assembly and Motion |
Abstract: On small length-scales, the mechanics of soft materials may be dominated by their interfacial properties as opposed to their bulk properties. These effects are described by equilibrium models of elasto-capillarity and wetting. In these… Show more Speaker: Michael Murrell, Yale |
|
| Red Stars over PAHs | Speaker: Charles Mentzer |
