Professor Holland's research involves theoretical studies of Bose-Einstein condensation in a dilute gas. One reason the recent experimental observation of this quantum degenerate system is so interesting is the possibility for providing detailed and accurate theory. Of particular interest are the modes of oscillation, the quantitative effect of interactions and loss processes, the behavior of a Bose-Einstein condensed gas undergoing evaporative cooling, and the effect of having a relatively small number of atoms on the thermodynamics.

Work has been done on the interesting prospect for an atom laser for which a condensate is a prerequisite. Examples of future research interests include damping processes of coherent excitations, quantum diffusion of the condensate phase, coupling of multicomponent condensates, and new theoretical methods for treating quantum kinetic theory.

Another area of Professor Holland's research is in the field of quantum optics where properties of laser fields and their interaction with matter is studied. Research is continuing on fundamental theoretical developments for treating dissipative processes. Describing dissipation as evolution subject to continuous measurement has led to an efficient way to study quantum diffusion of atoms in laser cooling. Other interests are in optical cavities and their interaction with atomic beams, and many aspects of quantum measurement theory.
