Dr. Pitonyak Gives Invited Talks at UVA and Italy Conferences

Dr. Daniel Pitonyak, assistant professor of physics, presented a pair of invited talks based on research supported by his recent National Science Foundation (NSF) grant to study the 3-dimensional structure of hadrons. Dr. Pitonyak presented “Updated QCD Global Analysis of SSAs: New Experimental Data and Constraints” as part of the QCD Evolution Workshop, which was held at the University of Virginia. He followed that presentation with a virtual invited talk—”Updated QCD Global Analysis of SSAs: H~, the Soffer Bound, and Lattice gT”—at the 6th International Workshop on Transverse Polarization Phenomena, which was hosted by Almo Collegio Borromeo in Pavia, Italy.

Dr. Veenhuizen Presents at National Conference on Glass Science

Dr. Keith Veenhuizen, assistant professor of physics, presented research at the 2022 Glass and Optical Materials Division meeting in Baltimore, Md. The presentation was based on results of a student-faculty research project undertaken by Olivia Magneson ’23 with Dr. Veenhuizen. The talk, “Phase-selective laser-induced crystallization of lead bismuth gallate glass,” reports how several crystal phases form preferentially at different temperatures in lead bismuth gallate glass. By varying the power and scanning speed of the laser irradiating the glass, the temperature profile can be controlled, through which the desired crystal phase can be formed. This talk was given at the Laser Interactions with Glasses session, which was organized by Dr. Veenhuizen in collaboration with Dr. Casey Schwarz of Ursinus College.

Dr. Walck Publishes Computational Physics Textbook

Dr. Scott N. Walck, professor of physics, published “Functional Programming for Physics Geeks,” with No Starch Press. The book, a culmination of a decade of Dr. Walck finding innovative ways to teach computational physics to LVC students, is available for pre-order at Amazon and Barnes and Noble. “Functional Programming for Physics Geeks” is the first book in the world to combine functional programming with physics at the undergraduate level.

Mathematical Physics Research Group Published in Quantum

Finite-Function-Encoding Quantum States,” the results of work done by LVC Mathematical Physics Research Group members Alex Heilman ’19 (physics), Ezekiel Wertz ’18 (physics), and Dr. David Lyons, professor of mathematical sciences, was published in the prestigious peer-reviewed science journal Quantum. This article is joint work with a research group at the Austrian Academy of Sciences in Vienna.

Dr. Veenhuizen, Jacob Franklin ’23, and Collin Barker ’19 Publish Student-Faculty Research

Student researcher Jacob Franklin ’23 (physics) and alumnus Collin Barker ’19 (physics) are co-authors with Dr. Keith Veenhuizen, assistant professor of physics, on an article published in the peer-reviewed journal Optical Materials. Dr. Veenhuizen is the lead author of the article, “The role of glass composition in the 3D laser fabrication of lithium niobate single crystal in lithium niobosilicate glass,” which explains how glass composition controls the nucleation and growth of crystals in glass and how this can be leveraged to create single crystals, a valuable result for making single crystal architectures in glass for optical applications. Co-authors of the article also include collaborators from Lehigh University and Corning Incorporated.

Dr. Pitonyak Co-Authors Paper for International Journal

Dr. Daniel Pitonyak, assistant professor of physics, co-authored a paper in the Journal of High-Energy Physics, “New tool for kinematic regime estimation in semi-inclusive deep-inelastic scattering,” with colleagues from Jefferson Lab, University of Torino, and Penn State Berks. They developed a phenomenological tool to guide the interpretation and analysis of high-energy electron-proton collisions, including an interactive notebook based on Machine Learning techniques. This research was supported by Dr. Pitonyak’s recent National Science Foundation (NSF) grant.

Malda ’22 and Gordon ’22 Join Dr. Pitonyak at Conference in NYC

Physics majors Michel Malda ’22 and Ben Gordon ’22 attended the APS April Meeting: Quarks to Cosmos in New York City this past weekend with Dr. Daniel Pitonyak, assistant professor of physics. There, Michel gave a talk titled “Updated QCD Global Analysis of Single Transverse-Spin Asymmetries with Additional Constraints from Experimental Data and Lattice QCD,” Ben presented “Analysis of the cos2φ and cosφ Modulations in Semi-Inclusive Deep-Inelastic Scatterring,” and Dr. Pitonyak discussed “Comprehensive Study of SSAs within the Jefferson Lab Angular Momentum (JAM) Global Analysis Framework.” The research was supported by Dr. Pitonyak’s National Science Foundation (NSF) grant to study the 3-dimensional structure of hadrons. 

Dr. Veenhuizen and Jacob Marsh ’25 Co-Author Article in Computational Materials Science

Dr. Keith Veenhuizen, assistant professor of physics, and physics major Jacob Marsh ’25 are co-authors on an article published with colleagues from Lehigh University in the journal Computational Materials Science. The article, “Determination of the structure of lithium niobosilicate glasses by molecular dynamics simulation with a new Nb-O potential,” discusses the development of a new interaction potential for modeling the structure of lithium niobosilicate glasses. Dr. Veenhuizen provided the experimental data supporting the model. Jacob and Dr. Veenhuizen collaborated with the lead author, Dr. Wei Sun, on analyzing the glass structure results generated from the computational modeling.

Dr. Pitonyak Gives Invited Seminar Talk

Dr. Daniel Pitonyak, assistant professor of physics, gave an invited seminar talk at the COMPASS Analysis Meeting, “First Global QCD Analysis of the TMD g1T from Semi-Inclusive DIS Data.” COMPASS is an experimental collaboration at CERN (European Organization for Nuclear Research) that studies the internal structure of protons and neutrons to discover more about their properties.

Dr. Veenhuizen, Olivia Magneson ’23, and Jacob Franklin ’23 Present at National Conference

Dr. Keith Veenhuizen, assistant professor of physics and director of cooperative engineering, Olivia Magneson ’23, and Jacob Franklin ’23 presented results of their research at the virtual Glass and Optical Materials Division (GOMD) 2021 Annual Meeting in December. Veenhuizen presented the talk, “Effect of glass composition on the laser-induced nucleation and growth of lithium niobate crystals in lithium niobosilicate glass.” Magneson gave a poster presentation titled, “Phase-selective laser-induced crystallization of lead bismuth gallate glass,” and Franklin gave a poster presentation titled, “Formation of continuous lithium niobate single crystals in lithium niobosilicate glass via femtosecond laser irradiation.” GOMD 2021 brings together researchers in industry and academia to share findings about glass science and technology.
