Professor Berman is engaged in theoretical research related to the interaction of radiation with matter. Of particular interest is the identification of atom-field configurations which can result in qualitatively new phenomena. Among topics his research group is currently investigating are the nonlinear spectroscopy of laser cooled atoms; coherent transients of cold atoms; coherent transient studies of atomic recoil accompanying absorption or emissions of radiation; theories of laser cooling; atomic deflection in optical fields; entangled states; atom interferometry, and spin squeezing as applied to quantum information processing.
Professor Berman is a Fellow of the American Physical Society.
