Projector Monte Carlo and exact diagonalisation with Rimu.jl
Joachim Brand
Rimu.jl aims to be an extensible platform for quantum many-body calculations. We have implemented the full configuration interaction quantum Monte Carlo (FCIQMC) algorithm and exact diagonalisation for quantum many-body models defined through a universal interface. The pure Julia implementation relies on native threading and uses MPI.jl for inter-node parallelism on the HPC. We will showcase solving an impurity problem in the Bose-Hubbard model where the linear matrix dimension exceeds 10^60.
