**Research Description:** Prof. Ciftan is developing the coherent state functional integral method and applying it to many interesting problems in condensed matter physics and quantum optics. This approach uses group theory to simplify the daunting problem of evaluating real time - real temperature solutions in statistical mechanics. In particular, his interests embrace applications of physics at very small distances and time scales relevant to new computer technologies. His past accomplishments include some of the original experimental work with lasers and quantum spectroscopy and studies of super radiance and optical bistability in quantum optics.
