Modeling
Models are abstract representations of the real world. A well-defined model is associated with a target system or phenomenon of interest, and can be used for either explanatory and/or predictive purposes. Modeling is the iterative process through which models and systems are brought into better agreement, either by refining the model or the target system itself. As a practice integral to experimental physics, modeling often appears as a learning goal for undergraduate physics laboratory courses at both the national and local levels.
Research-based Assessments
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla fringilla gravida sem ut pharetra. Proin nisl lectus, suscipit eget placerat eget, malesuada nec arcu. Mauris sollicitudin velit tempus, mollis elit a, lacinia lacus. Praesent blandit orci eu velit mattis consequat. Morbi sem eros, pellentesque eu convallis nec, sagittis quis orci. Sed egestas purus eu augue mattis ullamcorper. Etiam porttitor suscipit eros, vitae viverra nibh faucibus id. Integer eget mi at ex euismod malesuada.
Stark Deceleration
Our research uses supersonic expansion coupled with Stark deceleration to cool and slow polar molecules.
Molecular Spectroscopy
Our lab uses a Cryogenic Buffer-Gas Beam (CBGB) and a mid-infrared (mid-IR) spectroscopy setup for the purpose of studying the vibrational spectra of cold, gas-phase molecular clusters.
Ion-Molecule Reactions
Our lab directly laser cools trapped calcium ions (Ca+) down to milikelvin temperatures for the purpose of studying gas-phase cold chemical reactions.
The Physics Frontiers Centers (PFC) program supports university-based centers and institutes where the collective efforts of a larger group of individuals can enable transformational advances in the most promising research areas. The program is designed to foster major breakthroughs at the intellectual frontiers of physics by providing needed resources such as combinations of talents, skills, disciplines, and/or specialized infrastructure, not usually available to individual investigators or small groups, in an environment in which the collective efforts of the larger group can be shown to be seminal to promoting significant progress in the science and the education of students. PFCs also include creative, substantive activities aimed at enhancing education, broadening participation of traditionally underrepresented groups, and outreach to the scientific community and general public.
