Personal profile
SUMMARY of research interests (100 words)
- I work on Quantum Monte Carlo (QMC) algorithms, which use random sampling to solve the Schroedinger equation. I am mostly interested in developing the simulations themselves, though I do use them to reproduce results occasionally.
- Diffusion QMC methods rely on the fixed-node approximation of a trial wavefunction, in other words, the set of points for which the wavefunction is 0 is constant.
- Presently I am working with many-body backflow algorithms aiming to improve variational estimates of ground state nodal structure in these trial wavefunctions.
- I also have broader interests in condensed matter physics and scientific programming.
