My research interests are to develop the methods to perform simulations of quantum many-body systems, and to apply these methods to current problems in physics and chemistry. I use simulation methods (quantum Monte Carlo) that are based on imaginary time path integrals to sample the phase space of the quantum particles and are able to calculate, without approximation, properties of bosonic systems in equilibrium. We are interested in liquid and solid helium including droplets, and bose condensed systems, in particular, their superfluid properties. We are also interested in electronic systems, such as electrons in a uniform background, Wigner crystals, hydrogen under pressure and so forth. Exact methods for many-body fermion systems are not yet developed; that is another aspect of my research.
