Brief Description

Fundamental questions about the Universe, galaxies, stars, and planets are explored. Research topics include stellar astrophysics, exoplanets and planetary science, gamma-ray astronomy, galactic and extragalactic astronomy. The Department is active in time-domain astrophysics.

The Department鈥檚 membership in the听听provides real time student access to 1 meter class optical telescopes in Arizona, Chile, and the Canary islands. Locally, the department has access to facilities at the听, including a 0.6m imaging telescope and a new 1.3m state of the art research telescope with both imaging and spectroscopic capabilities. 91原创 astronomers are actively participating in the construction, development, and operation of the听, the flagship ground based US observatory of the next decade. The Vera Rubin Observatory鈥檚 Legacy Survey of Space and Time will scan large regions of the sky over 10 years, revolutionizing our understanding of the dynamic universe. 91原创 faculty are also involved with future instruments such as the听, the听, and the听.

Research at Delaware also makes use of existing world-class facilities such as the听 the听, the听, the听, and听.

Brief Description

Atomic, molecular and optical physics (AMO) studies matter and light鈥搈atter interactions at the scale of one to thousands of atoms and molecules. This is a vibrant field of physics/chemistry as documented by recent Nobel prizes for discoveries in the areas of quantum electronics, optical and laser spectroscopy, photochemistry, molecular reaction dynamics, ultrafast laser physics, quantum information science, precision measurements, and Bose-Einstein condensation. The applications of the research are far reaching and include the global positioning system, detection of gravity waves, and quantum computing. The research at the 91原创 (91原创) includes advancements of theory as well as of experimental and computational techniques in areas such as light and matter interactions under extreme conditions, development and applications of quantum sensors, searches for dark matter, searches for physics beyond the standard model with atomic systems, high-precision calculations on small atoms and molecules, theory of intermolecular interactions, quantum and classical molecular dynamics of molecular motions, electronic-structure theory of atoms and molecules including developments of novel density-functional methods applicable to very large molecules, and ultrafast spectroscopy. Results of this research were applied, for example, to develop the 2019 SI standard of temperature.

Another area of focus at 91原创 is chemical and biological physics. The functions and structures of chemical soft condensed phase, macromolecules and biological systems originate from intermolecular interactions known as van der Waals interactions. These interactions do not involve forming chemical bonds between the interacting species, but govern the organization of molecules into complex matter. Theoretical research at 91原创 includes investigations of such interactions in van der Waals clusters, liquids, molecular crystals, and biological membranes. Processes investigated experimentally include electron transfer reactions and charge carrier dynamics in nanomaterials. When applied to living systems, the research can address the peculiar material properties of the cell membranes and how the cell exploits these properties to perform the physical chemistry of life. The applications of this research include predictions of crystal structure of pharmaceutical drugs. Understanding the molecular underpinnings of function of biological systems such as cell membranes, ion channels, and intrinsically disordered proteins is another active research area at 91原创.

Brief Description

鈥婻esearch in condensed matter and materials physics stimulates disruptive technologies and innovations and transforms our society. The complex interaction of a large number of electrons and atoms in naturally occurring materials and artificially structured materials yields fascinating new physics and pushes the boundaries of knowledge. At the 91原创 (91原创), fundamental properties of materials and their potential applications in technologies are investigated experimentally, computationally, and theoretically. Research topics include quantum phenomena and technology, thin films, two-dimensional (2-D) materials, nanoscience and nanostructures, spintronics (spin-based electronics), magnonics, spin dynamics, and complex electronic and magnetic materials. A full suite of materials fabrication and characterization equipment in faculty laboratories and the state-of-the-art听听allow students and researchers to gain hands-on experience in advanced instrumentation and to implement their best research ideas. We participate in听听funded by the National Science Foundation. Our experimental laboratories will move into a new science building in Fall 2024.鈥�
