Physics Research at UNAPhysics Research at UNA
We believe a well rounded undergraduate physics program should include the opportunity for students to conduct original research under the supervision of a faculty member. All Physics majors are required to conduct a research project before completion of their degree. Students often present their research at state, regional and national conferences where they have frequently won student poster and talk competitions. Our physics faculty conduct research in optics, quantum mechanics and astronomy. See the physics faculty's pages to get more information about their research. Here are some recent projects.
Dr. Brian Thompson
Dr. Brian Thompson recently built an "optical tweezers" to trap micron-sized particles. This work involves specially configured lasers to manipulate small particles that are then studied. His students have won awards at state competitions for their research and have gone on to work in industry and to graduate programs. In the summer 0f 2012 Dr. Thompson spent a month in Italy conducting research.

Dr. Valery Dolmatov
Dr. Dolmatov's research focuses on theoretical atomic and molecular physics, particularly on studying of the structure of atoms and their interactions with photons in the vacuum ultraviolet (VUV) energy region, and incoming electron beams. Before joining UNA, Val conducted his research in atomic and molecular physics at several research institutions, including the Tashkent Physical-Technical Institute (Tashkent, Uzbekistan), and, as a visiting scientist, at the Ioffe Physical-Technical Institute (St. Petersburg, Russia), Hamburg University (Germany), Imperial College of London (UK), and Georgia State University (Atlanta, GA). Val has over 200 publications in the area of atomic and molecular physics, including about 80 research papers published in top refereed physics journals.
Dr. Dolmatov's publications have received well over 900 citations by fellow researchers to date; see Val’s profile at http://scholar.google.com/citations?user=rmXBgVkAAAAJ&hl=en.
Dr. Dolmatov's students regularly attend state, regional and national conferences to present their research and have gone on to graduate programs in physics.
Dr. Mel Blake
Dr. Blake investigates phenomena in the universe that change their properties over time. This primarily involved the study of binary and variable stars. Binary stars consist of pairs of stars that orbit one another in a similar way to the way the Earth orbits the Sun. Various phenomena can occur if the stars a close together, including mass exchanges that can lead to visible changes in their brightness or spectra.
Dr. Blake traveled to Chile in 2011 with student Daniel Johnson to obtain data to search for variable stars in old open clusters. More recently Dr. Blake completed a study of the binary star Delta Scorpius which is a Be star. These stars emit winds consisting of gas streaming from the stars surfaces. In 2011 Delta Scorpius' companion passed near the disk formed by the outflow of gas. Along with collaborators at Pisgah Astronomical Research Institute and undergraduate students Mary McDaniel and Taylor Garber, Dr. Blake studied the interaction of the companion star with the disk. The results were presented by Mary McDaniel at the PhysCon2012 national conference in Orlando, Florida hosted by the Sigma Pi Sigma Physics honors society, where she won first place in the astronomy student poster paper competition. She will present her results again at the spring meeting of the American Astronomical Society in Indianapolis, in June, 2013.
Dr. Blake's future work will use the UNA Observatory to obtain new data on various Be stars and other variable objects.
