Quantum Monte Carlo study of positron lifetimes in solids
K. A. Simula, J. E. Muff, I. Makkonen +1
We present an analysis of positron lifetimes in solids with unprecedented depth. Instead of modeling correlation effects with density functionals, we study positron-electron wave f…

Variational and Diffusion Quantum Monte Carlo Calculations with the CASINO Code
R. J. Needs, M. D. Towler, N. D. Drummond +2
We present an overview of the variational and diffusion quantum Monte Carlo methods as implemented in the CASINO program. We particularly focus on developments made in the last dec…

Stability of trions in coupled quantum wells modelled by two-dimensional bilayers
O. Witham, R. J. Hunt, N. D. Drummond
We report variational and diffusion quantum Monte Carlo calculations of the binding energies of indirect trions and biexcitons in ideal two-dimensional bilayer systems within the e…
