Colloquium – Newton Barbosa Neto – Photon Manipulation of Molecules

227 Gallalee Hall 514 University Blvd., Tuscaloosa, AL, United States

Speaker: Newton M. Barbosa Neto (Institute of Natural Sciences, Federal University of Pará, Brasil) Title: Photoinduced manipulation of conjugated polymers and molecules via sequential two-photon absorption Abstract: Solution processing of conjugated polymers into ordered self-assembled precursors has attracted great interest in the past years owing to the ability to manipulate their structural and physical properties.

Total Lunar Eclipse May 2022

Gallalee Hall Rooftop Observatory Gallalee Hall, Tuscaloosa, AL, United States

The University of Alabama Department of Physics and Astronomy invites you to come watch the upcoming Total Lunar Eclipse with us using the 16" telescope on the roof of Gallalee Hall! The event is free and open to the public. Partial eclipse begins at 9:29 pm, totality lasts from 10:29-11:59.  Doors will open at 9

Colloquium – Atreya Acharyya – Astronomy at the Highest Photon Energies

227 Gallalee Hall 514 University Blvd., Tuscaloosa, AL, United States

Speaker: Dr.Atreya Acharyya (University of Alabama) Astronomy at the Highest Photon Energies Abstract: Most astronomical telescopes observe thermal radiation. However, this does not include the most energetic gamma-rays photons, produced by large particle accelerators in space, which also act as tracers for cosmic-ray sources. While gamma-rays can be observed using space-based detectors, their relatively small

Colloquium – Leandro e Silva – Co-formation of the Milky Way’s thin and thick discs

227 Gallalee Hall 514 University Blvd., Tuscaloosa, AL, United States

Speaker: Dr. Leandro Beraldo e Silva (University of Michigan) Title: Co-formation of the Milky Way's thin and thick discs Abstract: Thin disc stars are younger than thick disc stars on average, and some models predict the thin disc to start forming only after the thick disc has formed, around 10 Gyr ago. According to these

Colloquium – Enrico Rossi – Quantum Metric and Correlated States in Two-dimensional System

227 Gallalee Hall 514 University Blvd., Tuscaloosa, AL, United States

Speaker: Dr. Enrico Rossi (William and Mary) Title: Quantum Metric and Correlated States in Two-dimensional System Abstract: In the past two decades some of the most interesting developments in condensed matter physics have resulted from the careful treatment of the effects of the Berry curvature in many-body systems. Exemplary is the discovery of topological insulators.

Colloquium – Luca Grandi – Looking for Dark Matter Signatures

227 Gallalee Hall 514 University Blvd., Tuscaloosa, AL, United States

Speaker: Luca Grandi (University of Chicago) Title: Looking for Dark Matter Signatures in a 6-tonne Liquid Xenon Target: XENONnT Abstract: A large set of astronomical and astrophysical measurements point towards a Universe with way more matter than what we can account for by looking around us. This missing mass is referred to as Dark Matter

Colloquium – Seong-Gon Kim – Flat-surface-assisted and self-regulated oxidation resistance of Cu(111)

227 Gallalee Hall 514 University Blvd., Tuscaloosa, AL, United States

Speaker: Seong-Gon Kim (Mississippi State University) Title: Flat-surface-assisted and self-regulated oxidation resistance of Cu(111) Abstract: Oxidation can deteriorate the properties of copper that are critical for its use, particularly in the semiconductor industry and electro-optics applications. This has prompted numerous studies exploring copper oxidation and possible passivation strategies. In situ observations have, for example, shown

Special Colloquium – Hunter Waite – Exploration of Jupiter and the Galilean Moons

227 Gallalee Hall 514 University Blvd., Tuscaloosa, AL, United States

Speaker: Dr. Hunter Waite Jr. (NASA, SwRI) Title: Jupiter and the Galilean Moons: The Ongoing NASA Juno Mission to Jupiter and Future Exploration of Europa by the NASA Clipper Mission Abstract: New results and future plans for planetary missions exploring the Jupiter system will be presented. Juno has been exploring the system for several years

Colloquium – Mariel Pettee – Machine Learning for High-Energy Particle Physics

227 Gallalee Hall 514 University Blvd., Tuscaloosa, AL, United States

Speaker: Dr. Mariel Pettee (LBNL) Title: Machine Learning for High-Energy Particle Physics Abstract: 10 years ago, in the summer of 2012, CERN announced the discovery of the Higgs boson, marking the end of a half-century quest to complete the Standard Model. Later that year, a deep neural network called AlexNet outperformed other models by an

Colloquium – Thejesh Bandi – Atomic Clocks: the workhorses of precision timing

227 Gallalee Hall 514 University Blvd., Tuscaloosa, AL, United States

Speaker: Thejesh Bandi Title: Atomic Clocks: the workhorses of precision timing Abstract: Precision timing is ubiquitous in our everyday lives. For instance, the workings of telecommunication networks, power grid synchronization, navigation – GPS/GNSS, imaging of Blackholes etc all need precision timing in its background, without which it is impossible to operate these technologies. The precision
